[cisco-bba] Best way to configure Cisco 1720, 2x WIC1-ADSL for MLPPP in the U.K.

[Steve Handscomb]

Good day to you.

I'm in the U.K. and our ISP has just started offering the ability to
bind ADSL lines much like ISDN.

So far, I've got the dial up working fine - the router dials up both
lines and bundles them together.

I'm then wanting to pass all data back to an IPCOP firewall (I have one
single fixed IP, with a further subnet of 8 IP's)

I enclose my current running-config for info, but it's the routing im
getting stuck with;  The basics are, the cisco should simply bridge
between the net and the firewall, but it is required to do the channel
bonding, so it (the cisco) must control the dial up / bonding of
channels.

Loosely, I've given the cisco router (FastEthernet0) an IP of
192.168.0.1, and the IPCOP red NIC (net side) 192.168.0.3

When I ping from IPCOP the router LEDs pulse as you would expect, but no
replies are going back to the IPCOP box.

Any help would be appreciated.

Regards

Steve Handscomb.


CISCO 1720 with 2x WIC1-ADSL
 
 
Setup
 
The Cisco router FastEthernet0 is set to 192.168.0.1
The firewall red NIC is set to 192.168.0.3
 
(Although it's irrelevant at the moment, the green NIC is set to
192.168.1.1, and the orange NIC (DMZ) will be 192.168.2.1)
 
As well as a single fixed IP - x.y.94.16, I've also another subnet
x.y.213.144/29 (144 through 151, of which 144 and 151 are unuseable, and
145 is the router address)
 
All IP's should pass to IPCOP, which will then sort them as I need them.
 
The config I've put together thus far is as follows:
 
ip name-server 213.208.106.212
ip name-server 213.208.106.213
!
