Unable to P2P between peer and exit node

[eveyraud]

Describe the problem

After disabling Windows Firewall and EDR, I am currently not able to connect my Windows and Linux peers in P2P together (only relayed connection). When I create a Linux VM in the same network than my Windows, the two can connect perfectly in P2P. I saw that NetBird wasn't UPnP and I created a rule to accept inbound and outbound connection on the UDP/51820 port (and even disabled FW as I said)

To Reproduce

Steps to reproduce the behavior:

1. Create self-hosted NetBird server
2. Connect a Linux peer
3. Connect a Windows peer
4. Authorize the two to communicate
5. Disable Windows Firewalls and EDR
6. Type command netbird status --detail
7. Look at Connection Type

Expected behavior

Connection to be P2P

Are you using NetBird Cloud?

I am using self-hosted NetBird

NetBird version

Linux : 0.49.0, Windows: 0.49.0

Is any other VPN software installed?

Yes, forticlient but it is disabled.

Have you tried these troubleshooting steps?

• [X] Reviewed client troubleshooting (if applicable)
• [X] Checked for newer NetBird versions
• [X] Searched for similar issues on GitHub (including closed ones)
• [X] Restarted the NetBird client
• [X] Disabled other VPN software
• [X] Checked firewall settings

Update The linux machine has the role of exit node for my Windows, when this role is removed from it, I am able to do P2P again.
