r7800: How to connect to admin console not using TCP (ethernet)
Hi
I have a Netgear R7800 with dd-wrt installed on it.
I was playing around with openvpn route settings and I have managed to set up a route for my subnet which means I cannot connect via tcp to configure it.
I am not sure exactly what I have done, but I think I (inadvertently) put a route command similar to: route 10.168.1.0 255.255.255.0 where 10.168.1.1 is the local ip address of my router and 10.168.1.x is my LAN subnet (not vpn subnet).
I seem to be able to ping the device, but cannot connect via ssh or http.
Somehow I need to get a connection so I can undo the bad configuration - does anyone know how I might do this ?
I thought I might be able to either:
manually change/set the local ip address of the router using physical hardware ? or other means ?
or connect to and change the configuration of the router without using tcp - via a serial port or something equivalent ?
Are either of those possible ?
If that is not possible is the only other option to do a board reset and completely reconfigure ?
If I do do a board reset I assume it simply resets with the firmware that is on the board (i.e the ddwrt firmware I have loaded) - is that the case ? Or does it squirrel away a default firmware somewhere and use that on reset ?
