Hi Csaba,

sorry for the delay,

I still don't have an answer about the dhcp server, but I managed to set a static route and it worked, however I am having one more problem.

As I am using a public machine remotely to use freeRouter, I have set the same IP address as the host machine, as it has not taken over the host interface.

With this the ping seems to be giving as a duplicate:

tetzner@pop-os:~$ ping 213.150.x.x

PING 213.150.x.x (213.150.x.x) 56(84) bytes of data.
64 bytes from 213.150.x.x: icmp_seq=1 ttl=42 time=182 ms
64 bytes from 213.150.x.x: icmp_seq=1 ttl=233 time=182 ms (DUP!)
64 bytes from 213.150.x.x: icmp_seq=2 ttl=42 time=182 ms

64 bytes from 213.150.x.x: icmp_seq=4 ttl=42 time=181 ms

64 bytes from 213.150.x.x: icmp_seq=4 ttl=233 time=181 ms (DUP!)

One solution I thought of is to create a reserved namespace and connect it to the interface via pcapInt or another tool, or even bridge the host and connect it to the freeRouter.
I was wondering if you had any tips on how I could solve this problem.

Sincerely,

Gabriel Tetzner Menegueti
