Is it possible to have two jails on the same host each one in a 
different private subnet, e.g. 192.168.1.0 and 10.33.1.0, and have 
routing between them working without issues?

I know it's possible to run jails with IPs in those two subnets but it 
seems there is no routing and I am not sure if it's because I can't 
configure my router properly or there is a more fundamental problem. One 
issue I see is that the jail can't have a different default gateway than 
the host, and that for now is 192.168.1.1, but I don't see a reason why 
10.33.1.0 wouldn't be able to use 192.168.1.1 as it's default gateway 
provided there is routing between those two subnets.
