Hello hintco,

You will have to connect to router locally and change the web access port to another number.

See the article http://www.tp-linkhome.com/tp-link-router/tl-r402m/i-want-to-build-a-web-server-on-the-lan-how-should-i-configure-the-tp-link-tl-r402m-router.html for more info

Hope this helps

Cheers

If you forwarded all the ports from external to the DMZ, you are no more able to connect from the external.

You should instead remote console to the DMZ server and then connect to the router from there.

If  you haven't done any huge settings in router then you can reset it. If you have not any other option to access it.

If you have done portforwarding to dmz then most of the ADSL router moved to port 8080

Adding a dmz will only affect external traffic, you will still be able to access the router using http on the local network.

If it's still giving you dhcp info, do an ipconfig and check the default gateway. Try http://ip

If that fails, try doing a scan on the ip using a free scan port utility to see if the http port has been changed from default

What kind of PC did you setup as the def. destination for all the traffic?

it's a windows host? a linux host? or what?

if it's a win box, try with remote desktop, if enabled
if it's a linux box, try with VNC to get a graphical console.

if it's a win box and you didn't enable RDP or a Linux box and you didn't enable VNC connections... then it's tricky, but doable.
Let me know.


@DUDES: guys, if i well understood the question, he's locked out from EXTERNAL, cause the router is REMOTE.
He configured the router to forward ALL the traffic to the DMZ host.

Hintco, please correct me if i'm wrong.

Do a remote port scan, find out which ports are open still. Making another ip a dmz shouldn't stop access to the router, as the dmz is only used for unspesified ports. There would still be a port open for remote access.

Otherwise use teamviewer and get someone onsite to remote you into a PC so you can http to the router from 'the other side'

Routers

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
