At work, we have a LAN, which is connected to the Internet using a DrayTek Vigor 120 ADSL2+ Ethernet Modem(*), which I once got after someone (Gordon, I believe) recommended it. It's been giving me a lot of pleasure. (Of course, that pleasure is mostly the absense of pain the previous BT router had been giving us.) One of the boxes on the LAN is set up as the gateway and, through a second interface, is connected to the modem. The box does all the DSL stuff. All works well. At the same time, another machine also had a direct connection to the Internet, connecting to a BT router through a second interface. That's useful for maintenance purposes. But we have now replaced that router with another DrayTek modem of the same make. And things don't really work.(**) There may be hundreds of reasons for this, but I wanted to check if my reasoning is correct. (1) Having two modems connected to machines on the same LAN - although on second interfaces on each machine - shouldn't be an issue, should it? (2) The modem creates its own mini-LAN for maintenance. So it assigns the machine IP address 192.168.2.10 through DHCP and assigns itself IPO address 192.168.2.1. This allows you to connect to its web interface. Is it a problem if both modems use the same IP addresses? I don't think either should be a problem - assuming one doesn't do funny things with the routing - but I have a tendency to make daft mistakes when designing a network.
