Re: 2 Nics and 2 subnets traffic configuration

Hi Brian,

What are you trying to ping on 192.168.2.x network? What did you set for
default gateway on clients on 192.168.2.x network (it should be
192.168.2.1)... Can you ping default gateway?

After you ping a resource on local subnet (e.g. anything on 192.168.2.x)
check the ARP table with this command:

arp -a

It should list MAC addresses of the computers that you pinged. If it doesn't
then something is wrong with cables or swtich/hub connection.
