I've got two routers. An asus rt-n16 which is the main router with the dhcp server turned on. A wrt54gl running as a wireless access point. Both have tomato firmware. I can remote log in to admin the asus using User.no-ip.org:1000 and I can log in fine. I configured the wrt to use the same login, but instead specified port 1001. I also created a port forwarding rule on the asus to forward port 1001 requests to the IP address of the WRT. But it doesn't work as I hoped. I don't have DDNS set up on the WRT. Is that necessary?
