I have a problem with a customer who owns a Cisco 836 DSL router.. he changed from a "home"-account (with dynamic IP) to a business-account (with one fix official IP), which causes a change of the username/password.
Unfortunately, the router couldn't connect to the internet after this change, because the ISP wasn't ready yet.
Now I had the idea, to try to make the change via remote from my office, when the ISP is ready.
- Discovering the actual (dynamic) IP address with whatismyip dot com or something else..
- Logging on to the router
- Set a "reload in 10" command (if something fails)
- Changing username/password
-> If I change this, does dis provoke a relogon of the working DSL-Connection?
-> If not, I had the idea to provoke this with a shut/no shut of the "int Di 1"..
But via Remote, the "shut"-command would kill my telnet-connection.. -> bad! :-)
Would it be possible to make a "macro", including both, the shut and no shut command, and then apply this macro to the int Di 1?
If yes, I hope, both commands would be executed.. Could this work?
If yes, the router should get a fix/non-dynamic IP, which I know already, and then I could relogon, make a "no reload in"-command and a "wr mem" and everything works fine? If not, it would reload in a couple minutes and it would run with the old config..!?
Did I forget something important?
Thanks in advance..
