There's neither "carnot" nor "Allied Telesis 3612TR" in your provided diagram so it's a bit difficult to follow you. It would be better if you provided a complete an up-to-date diagram. Anyway, I'll try to make use of my crystal ball: * The ISP you connect dalton to has given you control of the public network 142.103.107.128/25 or at least has given you some IP addresses on that range, right? * dalton's eth0 is configured with the public IP 142.103.107.137/25, right? * carnot's eth0 is configured with the public IP 142.103.107.138/25, right? * You expect carnot's eth0 being connected to dalton's eth1 by means of a crossover cable, right? If all my previous assumptions are right, then you need to configure an IP bridge between dalton's eth0 and eth1. That's all. In dalton's /etc/network/interfaces something along the following lines should do the trick (you should delete other ethN stanzas -you'll readd your VPN and other networks later, once you know your bridge is working properly, and you'd better have physical access to dalton since probably you'll need more than a try -oh, and make sure the iproute and bridge-utils packages are installed): auto br0 iface br0 inet static address 142.103.107.137 gateway 142.103.107.254 netmask 255.255.255.128 bridge_ports eth0 eth1 Cheers. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
