I've got a VOIP RT31P2 Linksys that is the gateway at 192.168.15.1, just as it was sent to me by the VOIP provider.  I've set up a WRT54GS, running DD-WRT, behind it, which is working as a wireless AP. At some point during this setup I was able to connect to the gateway through the wireless router to change settings without having to plug the Ethernet directly into the gateway. Although everything is working, otherwise, I have lost that ability.  When I connect Firefox to 10.10.15.1, I see the setup page on the wireless DD-WRT, when I try to connect to the gateway at 192.168.15.1 I get "page cannot be displayed".  When I ping 192.168.15.1 it's there in all it's glory.

 Am I correct that this isn't a RT31P2 gateway problem?  I've got my firewall in the Vista computer off, as usual. What info do I need to provide to the forum to make this situation clear? What might I have missed?

 Thanks.
