Simple soho setup

[trismegistus]

Hi

Does anybody have a simple working config that attaches a router to a BT ADSL modem (or other). The site is remote and I can't get the user to send me the config without truncating the text and making it unreadable.

The router is simply providing nat between a LAN and the dsl modem, but is not doing the job and I have no dsl facility to trial a config.

The dsl has genuine IP. We are using dhcp but no security enhancements etc. The router is a Soho71, but don't ask why we don't go straight into the dsl cloud from the router, its policy....

Hello - First of all the soho 71 is a dual ethernet router, so a modem is required to actually do the negotiation with the ISP. This why you cannot "go straight into the dsl cloud," which I am assuming you r referring to the DSLAM multiplexer. Basically this is the configuration you are looking for...I took this one from another thread actually. There was a few mistakes in the config orginally, but I added the changes. You need to find out the encapsulation type...in this case it is PPPOE. This is probably the most common on a DHCP ADSL line that I encounter. I do quite a bit of work with pacbell, on the business DSL side. They use AAL5snap encapsulation. Just so you know that this exact config may not work, there will be alterations.
