I have a 5510 that has 2 site to site vpn's that aren't working. Phase 1 and 2 are up, but no data packets are being sent. I have no idea what is going on. This just started randomly 2 days ago after working for weeks. Any help would be greatly appreciated. Thanks.
Just wanted to make sure as one of our ASAs had software 8.2(1) (If I remember right) and it encountered a situation where ASA just simply wouldnt pass the traffic to the VPN tunnel even though everything was fine.
Who knows though, maybe the same might happen in another software too. I dont recall finding any BugID for it.
We simply changed the active device in the failover. I presume with a single firewall setup a simple reboot would have done the same.
We also updated to 8.2(5) at that point.
We could see all the connections beeing formed on the ASA, but it seemed like they might have been passed to Internet unencrypted. Cant think of any explanation atleast.
