I have a remote tower that I need access to, its only connection is via a BB modem. It gets an IP address via dhcp. behind that I have my 5505. If i set up a l2l tunnel using the ip address, it works as it is supposed to. But if I register with Dyndns and try to us a name at the main site versus an IP address, it does not work. Dyndns is resolving the correct address, I know that if i use a name instead of an IP address i have to authenticate using a digital cert, i have trid all and still no joy. On the main station side i am getting this:
4 Aug 22 2012 12:14:13 713903 Group = 184.108.40.206, IP = 220.127.116.11, Can't find a valid tunnel group, aborting...!
That is because the group has a name, not an IP address.
