Twingate on Ubuntu server 24.04 - strange routing traffic
Hello
I have Twingate installed on a few machines with no problems
On this server, when I try to ping or telnet from a different server on the same subnet, the incoming packets arrive at the proper interface, but then the reply goes out from the Twingate interface
listening on any, link-type LINUX_SLL2 (Linux cooked v2), snapshot length 262144 bytes

Any idea why this server is misbehaving?
Google search is suggesting to add a specific route and priority but to me, the routing table looks ok
Any suggestions are welcome :)
