We've had a Cisco 800 series ADSL router installed on out DSL line for a
year or so now and I need to change a couple of port forwarding settings.
Initialy the phone company set up a few for me and I haven't had to change
them until now. I'd like to do it myself so that in the future if I have
more changes I can change them instead of having the phone company do it
for me. Here comes the kicker, the original settings were done using a
telnet session, I tried to use the web admin page on the router and managed
to bolix it up so completely, who knew enabling PAT would reset something
else, that I had to have the phone company get in and fix it. Took them 2
days to do it and management was screaming. What I need to know is how can
I back up the entire router so that if I screw up I can just redump the
settings back in and get back up and running ASAP. I remember the original
installer telling me something about the telnet session and recording the
settings to a file that I could just play back into the telnet session and
reset everything but I do not remember exactly how. The main reason I never
played with the router before is that I never could remember how I was told
to back it up in the first place and I'd really like to do this now so I
can play with VPN and other port forwarding stuff without having to worry
about getting billed for my screwups ;) Can anyone give me a short
tutorial on backing up this router?

Thanks

Bill

How do I restore this if/when I screw up the router in the future.

I just tried this and the 'run sh' command is not recognized. This is a
series 800 router if that matters.

Dyslexic be must I, this morning. Running the right command 'sh run' does
produce a settings report. Now how do I go about restoring the system
using this?
