We have a RH9 box that has 3 separate NICs with the following ips:

eth0 206.x.x.x
eth1 10.95.0.1
eth2 10.0.11.100

Up to this point, all traffic that came from the 10.95 went straight out to 206 (and vice versa). We would like to enable the 10.0.11 NIC but limited to allowing SNMP traffic from 10.95 to flow to 10.0.11 (and vice versa). All other traffic should continue to flow as it has in the past.

Unfortunately, I did not setup the box and I am unfamiliar with iptables. This doesn't sound too hard to do. Can somebody help me out? Let me know if you need any more info.

thanks
