Two subnets can't talk to each other? My Linux firewall question...
Mail server is 192.168.100.100
Firewall is 192.168.100.1 and 10.110.101.5 (and its gateway is 10.110.101.1 to the router)
I go to another workstation and ping the mail server. I can't. It times out.
I do the same from the mail server. It times out as well.
What am I doing wrong?
I'm a iptables newbie, so be gentle. Yes, I have read the docs, but would appreciate a little assist.

most likely, you need to add a route on the 10.110.101.1 router to tell it how to get to the other network
you will use route command to do this
how to do this at bootup/network iface up will depend on the distro, but you can manually do it at any time with the command above (as root or with sudo)
