Cisco 1841 to Vigor VPN

Guest · Post by **Guest** » Mon Dec 20, 2010 12:43 am

Hi All,

Im in desperate need of some help. Ive spent the last 48 hrs trawling the internet try to find how to set this up secessfully

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 when i try and connect to the external IP within the LAN. 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 vpns which all dial in to this router. They are setup to use ipsec with an ike pre-shared key. The dial in routers 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.

If anyone can help me i would really really appreciate it.

Please tell us more about the errors which you are getting. By the looks of it the configuration is fine.

First off when im entering this config i get down to crypto map cm-cryptomap and then the router is then uncontactable? so i can even put the correct acl in from then on. Im a complete novice at ciscos to be honest, managed to setup the bonded lines ok and some port forwarding but really am struggling here.

How can i debug the vpn connection or see the errors?

Thanks

Ive turned some sort of debugging on

Router# debug crypto verbose
Router# debug crypto isakmp
Router# term monitor
