if two nodes behind nat without public ip, can they make mesh vpn?
if two nodes A and B behind nat without public ip, can they make mesh vpn? if no, if there is node C with pub ip and port, can node A and B get each other's NATed pub ip and port and make a connexion? does your program make help?
What do you mean by "nat without public ip"? Do you mean no internet access or no dedicated IP?
In the first part I guess he's asking if there's local peer discovery? (A and B finding each other on the LAN) I'm very interested in having that too.
@whirm, I'm afraid, this is not supported right now unless you run a OpenDHT bootstrapping node in your LAN.
I mean A has 192.168.1.5 at home behind firewall and B has 172.16.1.3 in office behind firewall, both firewall are not configurable by me. If without a C with public ip, did they make mesh vpn each other by your wireguard-p2p? if I get a vpc with public ip and run your software, did A B are exchange information after connection established or all the information are relayed by C? thanks. because vpc is abroad, if all udp packet are relayed by C that is very slow, so I ask you if A and B can exchange udp directly,after getting each others NATed port and ip under the node C's help.
I think a similar question for which unfortunately I believe the answer is know. My ISP put me under a proxy and there is no transparent NAT. My public IP is not mine but of the proxy server. So any incoming connections will be refused while outgoing will be somewhat fine. Is there a way to establish a direct tunnel between A and B clients with similar network condition? I don't think so but I just discovered this project and I may try it.
@danielsouzat you could try a tool that wraps UDP in fake-TCP. I have seen a tool around for that but I cannot remember the name.
That depends on how you define "a lot". You'd probably have to add a TCP header which increases the package size by a few bytes and I think computation is negligible.
