I have a LinkSys E1000 v1. I've been using it for two years with DD-WRT v24 bridged (in some way that I forget) to my previous ISP's router.
I got a new ISP.
I factory reset the router, set up password. I initially set up client mode to connect to my new ISP's wifi router.
In client mode I can get a WAN IP. The client router shows up on the ISP's wifi router's device list. I can connect to the ISP router from a computer wired to the client router. I can do DNS lookups from the computer. HOWEVER, I cannot connect to any (other) internet services - either by name or by IP.
I reset it again and tried setting up in client bridge mode. In client bridge mode WAN is disabled (per wiki); otherwise the exact same set of information as above applies (shows up, can do DNS lookup, cannot connect to (other) internet services).
Have tried other devices plugged into the client router.
What's next for debugging? Any help is appreciated.
Is it different from the one used by the ISP router?
Is NAT enabled?
I've had it set up both in its own subnet and same subnet in Client mode. In Client Bridge mode it only "works" to the point of DNS lookup when it's in the same subnet.
I don't have any port fowarding rules enabled, but I tried a couple as an experiment before I replied, and didn't help. Also tried turning on UPnP, and that didn't help.
Debugging further I don't think this is a DD-WRT issue. I get the exact same behavior when a client router (whether or not it runs DD-WRT) is plugged into the ISP's router via ethernet. OTOH when a computer is plugged into the ISP's router it works fine.
