Hi All,

I've got a bit of a problem. I'm trying to setup 2 adsl lines bonded which our supplier fully supports. They have given me one IP and i requested a second as we needed to port forwarded 80 and 443 to two different servers.

My problem is with the below config. When connected up both ATM's are up when i use the show interface command and i can ping google for instance, but i go to my pc on the LAN and point the default gateway at the cisco 192.168.6.40 and i cannot get out on the internet. I have checked DNS which is configured but i'm a complete novice with cisco's at the moment and would appreciate some help please.

The equipment i have is a 1841 dual wic with ios 12.4.25 advanced security image.

Thanks in advance.

Hi Thanks for the reply, managed to get it working. However i'm struggling to port forward smtp. I've tried to allow port 80, 25, 442 but getting no where. Any ideas?

ip nat inside source static tcp 192.168.6.65 25 interface Dialer0 25
ip nat inside source static tcp 192.168.6.65 80 interface Dialer0 80

what exactly are you trying to do with ip nat outside source list nat-smtp pool isp-smtp??

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

I've got them problems sorted now, we still have an issue accessing the external ip 78.25.xxx.xxx through http locally on the lan.

I have ports 80 and 443 port forwarded for 78.25.xxx.xxx to our local mailserver 192.168.6.65. But all im presented with is page cannot be displayed. However if i try and access this address outside the lan then it works great?

My other problem I have is i would like to setup 7 vpn's which all dial in to this router. They are setup to use ipsec with an ike pre-shared key. The dial in router's are vigor 2600-2820 series and i was going to use the following config for the cisco but it hangs at crypto map cm-cryptomap.

Below is the full config less vpn info which works flawlessly with bonded adsl
