I have a Zyxel DSL router/firewall that is working without issue but I am unable to access the configuration interface any longer i.e. when I open a browser and type in http://the ip address of the router I get a 'page cannot be displayed' error.  I can ping the router and all rules are working e.g. mail delivery, remote access etc.  I was trying to figure out an issue recently and changed a setting on the interface, I can't remember what it was, and since then this problem has occurred and I now need to make some config changes.  Any suggestions?

if you know the configurations of the modem or hs a printout copy, the best suggestion is to do a factory reset and reconfigure the whole unit.

That's what I'm trying to avoid but I'm afraid it seems inevitable...

What model is it?

I'm a Zyxel reseller, I may be able to help.

Hi:

I see a solution has already been accepted, but just in case you don't have a backup of the config.,
or don't want to reconfigure the thing from scratch...

You say you can't reach the web interface....have you tried connecting via telnet to the command-line
interface? Most ZyXEL units will respond to that. If it's one of the router/firewall models, it may also have a console port on the rear of the unit. Have you tried connecting with that via the serial port on your PC?
