Hi,

I was trying to give access control for an external IP can access the web interface of my router, but I misunderstood the interface and end up making a huge mistake.
I let openned only telnet access, and only to the external IP.

Now, I'm looking for, without success, the telnet/cli command to give web access to my internal IP, or even full access to the router so I can correct the configuration after by the web interface.

If you know the command to give me that access would be great, because I do not want to have to reset all the configurations.

Also, my last modem had the option to backup the full configuration into a text file, if you know a way where I could do that it will facilitate in the case of having to redo the configurations.
