I'm new at this so please ber with me :) I have a laptop with two PCMCIA NICs I want to use as a firewall/gateway. Unfortunately I can't seem to get the darn thing working. I have a few questions I'm hoping someone can answer. Here's my setup: Laptop with two PCMCIA NICS One NIC (ed1) connected to a DSL router/modem DSL router/modem has a private ip (172.25.0.1) and acts as a DHCP server for my internal LAN PCs One NIC (ed2) connected to my internal LAN hub with an ip of 192.168.0.1 A picture would be: ISP | | [Global ip] ROUTER [172.25.0.1] | | [172.25.0.2] ed1 FIREWALL [192.168.0.1] ed2 | | LAN [192.168.0.2 ...] 1- When I use /stand/sysinstall to configure my interfaces it ask me for a default gateway. I'm setting ed1 to use 172.25.0.1 and ed2 to use172.25.0.2 but it seems that the last interface to brought up by /stand/sysinstall sets the default gateway for both interfaces? If I look at my rc.conf file, the deltas added by sysinstall have a line defaultrouter="..." and the ip specified is for the last interfac I brought up. Shouldn't there be one defaultrouter entry for each interface? 2- Which interface is my natd interface? I've tried both but when I run natd -v I can see that the real ip addresses are not really being translated but just used as is. Is this right?
