Bridged Router/Modem setup

cov · 05-19-2010, 04:45 AM

I'm using a Debian box as a gateway.

I'm planning on bridging my DLink 604T modem/router so that traffic on the LAN goes to my gateway (which only has one NIC). The Debian box is running a PPPoe application which I'm hoping to log into the ISP through the DLink.

I plan to configure the box as a squid transparent proxy.

Most Howtos I've seen use NAT with 2 NICs, eth0 for the LAN and eth1 for the Internet.

Can someone point me to a step-through to set up NAT for this?

you can follow those howto's all you need to change is your outside interface to ppp+

Great!

I guess ppp0 will do the trick?

No, sorry, when you said ppp+, you meant ppp+!

ppp0 will not do the trick ppp+ will because of the way the kernel assigns interfaces, in some cases if ppp did not clean up you get ppp1 instead of ppp0
