Hi folks, I have the Linux (Slackware 8.1) router and I use it to replace hardware router ( for example CISCO). This router is for only external IP addresses: I got 6 IPs from my ISP and of course to use them I made router on Linux box. My scheme is: Internet connection form radio modem | eth0 ----------------- | Linux box | ----------------- | eth1 ---------------- | switch | ---------------- | | --------- ---------- | FW1 | | FW2 | --------- ---------- | | Local network All network connections use ext IPS except local network. Everything works just fine. So my question is can I put two extra network cards to my Linux box and use the same PC as router for the second Internet connecton? Or do I have to use second one Linux box for it? eth0 and eth1 routing between first ISP IPs and eth2 and eht3 is routing between second one IPSP IPs? Thank you in advance Remus
