Important notices

Before you add a new report, we ask you kindly to acknowledge the following:

  • [x] I have read the contributing guide lines at https://github.com/opnsense/core/blob/master/CONTRIBUTING.md
  • [x] I am convinced that my issue is new after having checked both open and closed issues at https://github.com/opnsense/core/issues?q=is%3Aissue

Describe the bug

I posted the issue here but have yet to receive a response. Hence, this report. Please accept my apologies for potentially increasing the workload of opnsense's awesome team!

Upgraded from 23.x (latest release for business) to 24.4.1. Still on ISC DHCP with only IPv4; KEA not yet enabled. Intra- and Inter- VLAN packet routing works like a charm. No configuration or rule changes were made since. However, any outbound TCP (or sometimes UDP) packets in FW-->(any)VLAN direction on standard (e.g. 80, 443) or non-standard (e.g. 8080) ports do not get processed. ICMP pings to the same LAN hosts are fine. All other intra-VLAN nodes, inter-VLAN nodes, and even external nodes (e.g. web client on a cellular connection) can reach the address:ports in question. Just not the packets originating from FW. Example of such packets are telegraf metrics, crowdsec-lapi requests, or even simple requests from ssh/console like curl -vi --connect-timeout n <url> timeout.

Reverting to previous environment restores normalcy.

Steps to demonstrate issue

  1. 3 hosts in the mix here to illustrate the issue. a) Opnsense FW b) homeassistant (192.168.0.58) c) portainer (192.168.100.6)
  2. Check reachability of hosts on VLAN 3 (opt7, main, IP range 192.168.0.0/23) and then VLAN 100 (opt6, IP range 192.168.100.0/24) from Opnsense FW.
ping 192.168.0.58
PING 192.168.0.58 (192.168.0.58): 56 data bytes
64 bytes from 192.168.0.58: icmp_seq=0 ttl=64 time=0.409 ms
...

ping 192.168.100.6
PING 192.168.100.6 (192.168.100.6): 56 data bytes
64 bytes from 192.168.100.6: icmp_seq=0 ttl=64 time=0.369 ms
..
  1. Check routing towards the same hosts from Opnsense FW.
traceroute 192.168.0.58
traceroute to 192.168.0.58 (192.168.0.58), 64 hops max, 40 byte packets
 1  homeassistant (192.168.0.58)  0.464 ms  0.167 ms  0.175 ms
...
traceroute 192.168.100.6
traceroute to 192.168.100.6 (192.168.100.6), 64 hops max, 40 byte packets
 1  portainer (192.168.100.6)  0.359 ms  0.133 ms  0.241 ms
  1. Check for port 443 exposure and attempt a simple curl request from one host to another - to test inter-VLAN reachability at application level. It works as intended.

Expected behavior

Opnsense should establish HTTPS/TCP connection, or even basic TCP connection to hosts on various VLANs.

Describe alternatives you considered

Please refer to above. Reverting to Opnsense 23.x (last known business version) restores normalcy.

Additional context

Few additional considerations which i grappled with:

  1. Does this issue always happen? Mostly yes, but every so often (once in a few hours or so) a TCP request in FW-->Host direction slips through. Evidence:
#nc -4znvw 10 192.168.0.58 443
Connection to 192.168.0.58 443 port [tcp/*] succeeded!
<!-- immediately following which another series of requests fail -->
...
#nc -4znvw 10 192.168.0.58 443
nc: connect to 192.168.0.58 port 443 (tcp) failed: Operation timed out
# nc -4znvw 10 192.168.0.58 443
nc: connect to 192.168.0.58 port 443 (tcp) failed: Operation timed out
  1. What is going on at TCP/IPv4 level? a. Are the FW originating HTTP(s) over TCP packets sent over the wire? Yes b. If so, is the switch network eating it up? (due to say bad VLAN configuration No c. Is the receiving host not responding at TCP level? ** No**. Receiving host does issue TCP SYN ACKs d. Are receiving hosts packets blocked by FW rules? Answer: No e. Are receiving hosts packets received at the FW interface? Answer: Yes

Packet capture from opt6 (VLAN 100) to illustrate packet behavior can be seen below. Same behavior for main/opt7 interface is also observed. :

  1. Is there an MTU mismatch issue here? Step /2/ shows FW with mtu:9000 (downsampled at ether layer) with host mtu:1500 (downsampled at ether layer). Changing host mtu to be same as FW results in same behavior. Please see attached tcpdump.zip which includes pcap and json.

tcpdump.zip

  1. Could there be an intermittent issue w/ network drivers for the ice card involved? ** Doesn't seem so**, Also, if that were to be the case then it should manifest across all VLANs? There are certain oddities about ice messages but these seemed also to be there in 23.x (if memory serves me right).

if 23.10.x works as expected but 24.1 doesn't, the first question is what the difference is in generated ruleset (/tmp/rules.debug). Would it be possible to collect both on the exact same configuration? Common issues in these cases relate to reply-to and route-to rules .

AdSchellevis avatar Jul 06 '24 20:07 AdSchellevis

@AdSchellevis Many thanks for the prompt reply!

firmware-->changelog history:

Version	Date	
24.4.1 (installed)	2024-06-20	
24.4	2024-04-30	
23.10.3	2024-03-28

Now I notice that 23.x boot environment is no longer visible. I only see the base snapshot manually created my me back in 2022!

bectl list -a
BE/Dataset/Snapshot  Active Mountpoint Space Created

default
  zroot/ROOT/default NR     /          8.44G 2022-10-25 01:28

Perhaps the reboot after 24.x cleared previous boot environments?

What would the sequence of involved steps to furnish you with appropriate /tmp/rules.debug now be? 0. perform bectl create 24.4.1-buggy

  1. perform fresh install of 23.10 via console (nano image) or opnsense-revert -kr 23.10
  2. import current config
  3. save /tmp/rules.debug
  4. hopefully, if its a working system at /1/ then follow normal upgrade system prompts via web GUI
  5. save /tmp/rules.debug
  6. compare and share here

morikplay avatar Jul 06 '24 21:07 morikplay

A reinstall with 23.10 and update to the latest version in the 23.10 branch would be best indeed, then test if the issue is indeed not there and collect evidence.

If you want to exclude pf as most likely cause of your issue before reinstalling, I sometimes temporary disable pf as well using pfctl -d then check local connectivity and enable it again (pfctl -d). When local communication works without pf enabled, it's either a policy based routing rule (route-to/reply-to) or a nat issue.

AdSchellevis avatar Jul 07 '24 08:07 AdSchellevis

Thank @AdSchellevis. I'll be remote (to FW in question) for the next few weeks. So, a full blown downgrade w/ console access might be a tall order until then.

The following didn't make a dent in the issue:

  1. Disable pf using pfctl -d
  2. curl failed
root@MorikCage:~ # curl -vi --connect-timeout 5 http://homeassistant.esco.ghaar
* Host homeassistant.esco.ghaar:80 was resolved.
* IPv6: (none)
* IPv4: 192.168.0.58
*   Trying 192.168.0.58:80...
* ipv4 connect timeout after 4999ms, move on!
* Failed to connect to homeassistant.esco.ghaar port 80 after 5002 ms: Timeout was reached
* Closing connection
curl: (28) Failed to connect to homeassistant.esco.ghaar port 80 after 5002 ms: Timeout was reached
  1. Tried /2/ again after a few minutes. Same result. Although i suspect state tables were still active?
  2. Enabled pf via pfctl -e

I could also attempt a step 2.5 with pfctl -F all to see whether that helps. But, I doubt it as my rules haven't changed between the two releases.

Would there be any other files besides:

  • /tmp/rules.debug
  • dmesg >> /tmp/dmsg.out from 23.10 which you'd recommend for collection to aid in the diagnosis? I ask so that when I do the downgrade I can collect the right information.

morikplay avatar Jul 07 '24 17:07 morikplay

well, if it doesn't work when pf is disabled in full (state table doesn't matter in that case), the question is if there is a valid default gateway installed and the interface used has a valid netmask.

netstat -nr4
ifconfig

AdSchellevis avatar Jul 07 '24 17:07 AdSchellevis

  • LAN (from any host on any VLAN) <--> LAN (from any host on any VLAN), rules permitting, works as expected
  • LAN (from any host on any VLAN) --> WAN (e.g. google, bing, my own external websites) work wonderfully as well.
  • Reverse direction also works for HTTP (80-->443), HTTPS (443) and Wireguard port. No other ports are exposed externally. Meaning WAN --> LAN (via NAT redirect) works as expected. which is why this problem is puzzling.

Just to be sure, internet hosts also don't work or only access to 192.168.0.58?

You may remove sensitive data from the output by the way, for debugging we don't need mac addresses and exact netblocks.

AdSchellevis avatar Jul 08 '24 07:07 AdSchellevis

@AdSchellevis, thank you. I'll remove MAC addresses and such shortly.

Yes, access to internet (NAT) isn't a problem. The issue is only for traffic which originates from OpnSense e.g. syslog to a syslog server on lan, or Telegraf metrics destined for influxdb on lan, CrowdSec http notification to a LAPI on lan, simple curl requests to anywhere on any lan etc.

morikplay avatar Jul 08 '24 19:07 morikplay

I wouldn't suspect the firewall to be honest, my next step would be to capture the traffic on both ends (packet capture on the firewall and on the target for the traffic between both hosts).

These type of issues usually relate to wrong gateways on the client in which case traffic does not return to the expected host.

AdSchellevis avatar Jul 09 '24 06:07 AdSchellevis

Thank you for your continued guidance @AdSchellevis . Initially, I too had the suspicion that it must have been me (by virtue of network configuration changes) which would've caused this issue. But, few aspects don't support that conclusion:

  1. Literally the only change was Opnsense 23.10-->24.4. Opnsense originated traffic towards VLAN was fine up to 23.x.
  2. Looking at the tcpdump captures at Opnsense interface (opt6) from initial message, one can see that opt6 (same goes for other opt interfaces) does receive a SYN-ACK in response to its SYN. But, application logic (i.e. something above the TCP/IPv4 stack in opnsense) does not receive delivery of the SYN-ACKs. This causes TCP/IPv4 stack on opnsense to repeat SYN. Re-pasting for brevity

  1. Both curl and nc exhibit really odd behavior. Latter recognizes tcp/443 as udp/443.
  2. Intermittent allowance of connection establishment for FW-originated traffic from FW-->VLAN host(s) tells me its something to do w/ pf and/or rules.
#nc -4znvw 10 192.168.0.58 443
Connection to 192.168.0.58 443 port [tcp/*] succeeded!

  1. If gateways were incorrectly configured on client(s) (pretty much all of the 150+ hosts in the network) then reachability issues would've manifested one way or another. Packet drop stats on those hosts are 0 when other LAN hosts / clients are involved.
  2. To match /2/, attached is tcpdump from the peer (192.168.100.21:8080). I picked a different host (than .100.6) in VLAN-100 on a non-standard port to illustrate the point further. As can be seen, the host keeps getting re-transmissions of SYN from FW (caused as a result of curl -vi --connect-timeout 5 http://192.168.100.21:8080. At the FW interface, NIC receives the packet, but doesn't respond with ACK. from_host.zip

I'm a bit out of clues I'm afraid, I suspect there is a logical explanation, but tracking this exceeds my current community support time.
