The debug output shows that you are transmitting ISAKMP but are not receiving any ISAKMP response. Can you verify that you have connectivity to the peer at 68.8.56.2?

Can you verify that the peer at 68.8.56.2 is receiving your ISAKMP attempts to negotiate? Does the peer believe that it is sending to you?

It is a possibility that there is some issue on the other device or it may be that there is some problem in between that is disrupting the ISAKMP negotiations.

Re: VPN Error

Hi

Can you post more info about your setup where you are getting this error message?

have you changed something recently with respect to the isp connection or configuration or hardware ?

also since when you are getting this error (from the beginning of this connection or after any changes in the network)?

Do provide more info on the connectivity which you are using for this vpn connectivity.

Re: VPN Error

Hi Rick,

IPSEC traffic was having issue with One Service Provider, moving to another Service Provider resolved the issue.

Its not easy to analyze an issue when all was well and no changes done.  (( OR )) there is some simple troubleshooting tips for IPSEC

:-)  Thanks Rick
