Cisco – Setting up a Cisco router for dial in access

ciscomodemrouter

Our MPLS provider needs our routers to be setup with modems so that they can dial in and make config changes when necessary. I have connected the modem to the router (Cisco 2600) via the aux port. When I dial the # for the modem, it rings, but never answers. I'm guessing there's something in the router config that I need to setup, but I have no idea what it is. Any ideas?

The laziest way is almost certainly just to go:

async-1#terminal monitor
async-1#debug confmodem
Modem Configuration Database debugging is on
async-1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
async-1(config)#line 1
async-1(config-line)#modem autoconfigure discovery
async-1(config-line)#

The real answer is set &S0=1 in your modemcap (well probably) Actually you probably want to look at the whole list of vendor init strings http://www.cisco.com/en/US/tech/tk801/tk36/technologies_tech_note09186a008009428b.shtml#specinitialcomm (that page also has some info on creating a chatscript and altering modemcaps)

Cisco NAT Config for DSL

This can't be that hard -- but I'm thinking I'm pretty lame. Any advice?

I hate to suggest something non-cisco, but you are running older end of life'd Cisco routers -- so I will. When my PIX 506e burned up, I replaced it with a tinsy system from LogicSupply running Vyatta and have been nothing but impressed.

I just shipped out a production VMWare machine running 6 static IP's, 3 internal networks (10.0.1.0/24, 10.0.2.0/24, 10.0.3.0/24), all natting out of one IP, and all 6 external IP's randomly port forwarding inward with no respect for any one to one mappings.

If you had a spare machine you could replace the 2600 with, or purchase something solid state from LogicSupply -- you would be extremely impressed with Vyatta .. and want to shoot yourself in the foot for using the 2600 for anything but a doorstop.

It goes without saying -- but you've posted your private IP's, router, router config, and hashed password online. Your going to change that password right?

Cisco IOS router MAC or IP address filtering

You might want to see Filters Using MAC-Based ACLs.

Can you provide details about the hardware / software you're running?

Update:

So based on the information you supplied I believe this is the correct answer. From the linked document above:

AP# configure terminal
AP<config># access-list 700 deny 0040.96a5.b5d4 0000.0000.0000

!--- This ACL denies all traffic to and from 
!--- the client with MAC address 0040.96a5.b5d4.

AP<config># interface Dot11Radio0.1


!--- Or whatever the radio interface is

AP<config># dot11 association mac-list 700
