I have a 4-port Ethernet card (D-Link DFE-570TX - btw, tulip module) and use it for now with two ADSL connection and the internal LAN:

eth0 is the fixed connection via ADSL, with IP 61.219.255.186 eth1 is a PPPoE connection (ADSL), with a static IP 203.204.5.215 eth2 is not connected (reserved for the third line) eth3 is the internal LAN

I use SuSE Linux with kernel 2.4.6 rp-pppoe-3.3

adsl-status:

To test if the link via PPPoE works I added: route add -net 202.58.118.0 netmask 255.255.255.0 ppp0

netstat -rn:

ping 202.58.118.12 (that is ftp.suse.com ;-) ) reports 100% loss, as well as traceroute (from the server) From the internal LAN I cannot test since the second firewall settings eth1:eth3 is not setup yet.

I am sure I just forgot something, but cannot find it!

Can anybody give me a hint please?

bye
