Routing issues
I have a following setup: Debian with iptables firewalling out several
computers with routable IP addresses. In order to get responses from the
net, I had to manually add routing table with 'route add -host' for each
computer.
routing table is like this:
host1.domain * 255.255.255.255 UH 0 0 0 eth1
host2.domain * 255.255.255.255 UH 0 0 0 eth1
host3.domain * 255.255.255.255 UH 0 0 0 eth1
localnet * 255.255.255.0 U 0 0 0 eth0
localnet * 255.255.255.0 U 0 0 0 eth1
default maingateway 0.0.0.0 UG 0 0 0 eth0
(eth0 is outgoing interface, eth1 is local)
The question is: This firewall is supposed to be built in front of two C
subnets (on a same cable, it's a feature of a CISCO ruter, don't ask me
details:).
What kind of routing table must be built? Is it OK to put route
add -net xxx.yyy.zz1.0 dev eth1
add -net xxx.yyy.zz2.0 dev eth1 ?
I have a small margin for errors, because there are servers on that subnets
which must be up 0-24 so I rather ask here before doing some nasty things :)
