Update: Forget this, I just bought a new modem. Not that it works either, but it's better than this I don't know if anyone can help me, but I've searched everywhere and not been able to find any information. I have a WRT54G for wireless and an ethernet ADSL router (DSL-906, PPPoATM to plus.net, static IP) for internet connectivity. At the moment, the ADSL router is just plugged into the switch and acting as a gateway. What I'd like to be able to do is to plug the ADSL router into the WAN port on the wrt54 - basically, to use it as an ADSL modem so I can use VPN (no working support on the router). I figured that PPTP is the way to go for this, so I enabled PPTP on the ADSL router. I then tried to configure PPTP on the Linksys (2.02.7 firmware). The configuration requires: Internet IP netmask gateway IP Username/password I'm fine with all those except the gateway IP. I've tried the IP address of the next hop upstream, but that is on a different subnet to the internet IP and the Linksys won't accept it. Has anyone managed to configure an ADSL router in half-bridge (modem-like) mode like this? Or am I going to have to buy an ethernet ADSL modem?
