I'm trying to create 2 independant secured dhcp networks. Right now I have 3 nic's up and running. The first being PPPOE(eth1) and the second I named the Green network(eth0) with a gateway of 192.168.0.1 and a range of 192.168.0.2 to 5 and the last I named the Blue network(eth2) with a gateway of 192.168.1.1 and a range of 192.168.1.2 to 5. Right now they both function well except for the fact that I can access services between the two networks which I don't want. Both need internet access. I'm mainly concerned about anyone gaining access to the Green network from the Blue network where most of the web browsing is taking place. Right now under Network Security-->Packet Filter I have as rule 1 Green(network)-->Any-->Any. As rule 2 I have Blue(network)-->Any-->Any. Under Nat-->Masquerading I have Green(network)-->PPPOE and Blue(network)-->PPPOE. I guess my rules are wrong somewhere but I don't understand how to create rules to secure the networks from one another. Any help would be appreciated. Thanks...
