G'Dau Dusty_bin,
I am assuming its the same as the TG784.
Create a new User
Do the following to create an appropriate user.
first before resetting the users - just in case its an IE7 lockout which can occur after changing the Administrator password.
system config digestauth=disabled
user flush
exit
Telnet to the router again but this time use the username root with no password.
user add name Admin password awordortwo role SuperUser defuser enabled defremadmin enabled deflocadmin enabled
Further options may be requested, however defaults or blanks are allowed. Check that access to the GUI is now allowed using the new details.
Allow remote access to GUI or Telnet
Users that want to remotely manage their routers either through the GUI or via telnet can. First create a user as above, this gives that user privilege to manage remotely, then telnet to the router.
service system ifadd name HTTP group wan
service system ifadd name HTTPs group wan
service system ifadd name TELNET group wan
This of course opens the router up to anyone on the internet. To secure access to an IP or range of IP's type the following.
service system ipadd name HTTP ip 212.23.9.250
service system ipadd name HTTPs ip 82.69.227.30/29
service system ipadd name TELNET ip 212.23.9.250-212.23.9.259
If locking down to IP, remember that it takes effect immediately. If you are connected to the router via telnet from the local network and you lock telnet down to a WAN IP you will be instantly disconnected and be unable to connect from anywhere other than the WAN IP specified. Be sure to add the IP you are currently connected from first.
