Hi,
I was working on setting NAT up on my 2811, through the CLI, and created an interface named "NVIO", which seems to be getting in the way of traffic.  IT was created in the fa0/1 interface config mode, and now I can't seem to find how to remove.  If i do the following
router#config t
(router-config)int VNIO
I get a unrecognized interface.  
Any suggestions?

Is it called VNIO or NVIO now?
Can you post the output of `sh run all` or if "all" is not supported on your IOS version, post `sh run`.

If it's possible to reboot this router, that might also be an option if you haven't `wr`'ed the changes already.

It was written to memory (sadly) after I made another needed change (save one thing at a time folks) shows up as NVIO, not VNIO, typo in the tread not in my actual use.  Heres my running config

Is it desired that Fa0/1 is shut?

Try:

conf t

int Fa0/1

no ip nat enable

I've tried that and it takes the command but doesn't kill the interface.
I shut Fa0/1 to see if it'd help with the NAT issue, as it was set up in the fa0/1 config menu.

Thanks!

Ok, well I did the fiollwing, not too sure what fixed it though:

config t
int fa0/1
no ip nat enable
no ip nat outside
no ip nat inside
no ip nat static-host

then rebooted
After reboot NVIO was gone, Voip phone on circuit auto rebooted and now is placing calls.  I'm awarding full points.  
Thanks for the help!

That's exactly why the `sh run all` output would have been interesting (if supported by your IOS version). It shows some hidden configuration variables too which the normal `sh run` doesn't show.

Good to hear that it at least pointed you into the right direction and thanks for awarding full points!
