I have 2 network interface connecting each on a specific network.
the default gw is 192.168.50.1 on enp6s0.
The second interface is connecting to network 192.168.100.0/24 with address 192.168.100.26 as enp7s0. I am unable to access an address on 192.168.100.0/24 network. I tried everything I know, to no sucess. I have install a jailmaker docker on interface enp7s0, from the docker container I have no issue access any address on network 196.168.100.0/26. itried also to add a route for 192.168.100.0/24 with Gateway address 192.168.100.1., with a response that route already exist. I missing something, just don’t what.Anyone can help figure out what is missing ?
Here some command I tried with the result:
