Before it was working,and now router is not responding
According to wireshark when i try to connect, UDP paccket with source port 1310 is sent to 62515 destination port, and then 4 ISAKMP Aggressive packets from 1311 to 500
Router accepts packet on 500 port (according to permit any log rule.. from 1310 to 62515 seems not to reach the router)
and nothing occurs (debug crypto engine is on)
ACL is off on router and firewall on PC also

Why all of a sudden does this error occur?
I made no changes to the VPN or router. It has been working great for a good while and now all of sudden it is throwing an error:
Secure VPN Connection terminated locally by the Client.
Reason 412: The remote peer is no longer responding.
Connection terminated on: Jul 17, 2012 13:00:58 Duration: 0 day(s), 00:00.00
There were no modifications/changes to the VPN, why this error now?
Could you please run the following command on the Router?
debug crypto isakmp
debug crypto ipsec
Try to connect and attach the outputs.
On the other hand, have you tried to connect directly to the Router (I mean, not over the Internet)?
My router is under warranty at the moment. The awesome Cisco Support Team is handling the problem right now. Whatever the results are going to be posted here to help others in assisting with the same problem.
I have asked the question, during the whole time the VPN has been running flawlessly, as to why all of a sudden this error was thrown?
