I am in process of moving from 2910 to 2850. When using 2910 router, I can enter the WAN address:port and it resolves everything correctly ( I have 2 WANS). This is handy for things like IPAD apps (but others) where the WAN IP is coded into the app (e.g. IP camera viewer) - but I can still use it when locally attached. I can't seem to get the 2850 to do this - it just sits there and then says there is a problem. If I use the 2nd WAN address (dyndns) then it resolves. My pc is tied to WAN1.

Any help please?

Solved - a reboot seemed to sort it.
