I have configured remote access VPN on my ASA-5510 Firewall 8.4(2) using DynDNS as I do not have static IP addresses. Everything was working fine but now my users cannot access the VPN tunnel from outside. (No changes have been made on the Firewall since the last VPN setup, after which everything was working optimally).
Users are receiving the following error message:
Secure VPN connection terminated locally by the Client. Reason 412: the remote peer is no longer responding.
Also the Host name and IP address is changing properly and seems like there is no problem from Dyn DNS side. All the NAT routes are also in places and seems to be working fine but my users cannot connect.
I will highly appreciate if someone could help me on this.
