Here is my Setup...
I have two windows VM's are set at 192.168.51.100 and 192.168.52.100.
These two windows machines are able to ping each other and each router. I am unable to ping from the routers to the remote network, say from 192.168.51.1 to 192.168.52.100 or .1
The persistent IP Tables (rules.v4 file) are as follows: They are the same iptables on both routers.
*nat

I did find out that I can ping the remote networks by forcing it to go out a specific IP.
ping 192.168.52.100 -I 192.168.51.1
But trying to use anything else doesn't work(wg0,ens192,ens160). Is there a way to not have to specify the IP address?
