Site-to-Site VPN only working in bidirectional mode

Unanswered Question
Mar 15th, 2010


I have a site-to-site VPN between two ASA 5510 working. One of the ASAs is connected to two ISPs and therefor has two public IPs. To make the VPN also working during a downtime of the main ISP I added the public IP of the backup connection to the list of peer addresses at the other ASA. I further set the connection type of that ASA to "originate-only" and of the ASA connected to two ISPs to "answer-only" but as soon as I apply these changes the VPN is not established anymore.

Any ideas? Do I have to initiate the VPN from the "originate-only" site somehow? I tried it by connecting to a host at the "answer-only" site from there but the VPN was not established.



I have this problem too.
