Can someone explain how this works to me?
On an OpenBSD router/firewall with 3 nic cards in it, if I send packets from the box (ex. ping) do the packets go through any of the other interfaces besides fxp0 (the external interface which goes to the cable modem)? The reason I ask is, I'm still having problems setting up my box. Do I have to set up NAT and IPFilter to allow packets out that originate at the actual firewall? If so, whats the IP address of firewall? I figured that the IP for the firewall (in terms of packets coming from) would have the IP of the external nic (fxp0) and since that IP is routable there is no need to have them natted? Obviously, since it still isn't running, I'm not understanding something.
Also, is there any possability of me having problems because all 3 nics are the same type/brand? They're all using different IRQ's and I'm pretty damn sure they're all using different mac addresses.
