You shouldn't need the access-list to allow telnet access.

 I would remove the access-list 12 and access-class 12 in

I'm sure you have an enable password set, I think this is required to enable telnet access as well.

Cheers!

But I am trying to telnet from the outside (internet) to the WAN (serial interface ip).  Are you sure I do not need an access-list?
Maybe I only have an enable secret set, and not an enable password.

Hi Brasslan,
Yep, you are right.  I have a test router and I added the ACCESS-CLASS 12 IN command.  From that point on, I was not able to telnet to the router from the INSIDE< which I have always been able to do before.  Once I removed the ACCESS-CLASS 12, I was able to telnet to the router from the inside.

But I still cannot telnet to the router's WAN/Serial/Public ip interface.  How the heck do you do it?  Sounds simple, but I guess the occasion has never come up before to do this.

Thanks

So you are saying that after removing those two access lines, then you can telnet in to the LAN interface but not the WAN interface???

Honestly,, no :-(

Can you ping the WAN int?
Do you have SSH setup on outside int?
Any other access-lists in the router that would get in the way?

I figured out what it was:
I am tired, first of all!
I did not add the correct ip address to the ACCESS-CLASS x.x.x.x IN command
The whole issue was a static nat command that changed the destination ip to an internal ip for ALL packets, even the one in which I was trying to telnet to the wan interface of the router
