I'm trying to establish a VPN Tunnel with a router having a dynamic IP. I'm using DDNS.
"crypto isakmp key xxx hostname xxx no-xauth"
in my central cisco router (2811, IOS 12.4) i always get the error
"No pre-shared Key with (IPADDRESS of the router)"
If I use "
crypto isakmp key 1234 address (IPADDRESS of the router) no-xauth"
everything works fine.
Seems like the cisco is not resolving the DNS. But when I do a telnet on the cisco and a ping at DYNDNSNAME the Hostname is resolved and the ping works fine.
Any idea why it won't work?
