I am a new of ASA. I setup several VPN tunnels between Data Centre, Headoffice, Site A and Site B. (Pls refer attachment)
Alls VPN tunnel are up. when I setup ASA in head-office as "VPN hub" so that Users in Site A and Site B are able to access the resources in Data Centre through ASA 5510
Everything is fine excecpt that the tunnel between Site A and Data Centre. Users are able to access the resources in Data Centre for 6-7 hrs only. Then, the VPN tunnel is dropped. When it happens, I checked that the VPN tunnel between Site A and head office is UP.
How to rebulid the the tunnel between Site A and Data Centre. I manually logoff the VPN tunnel and Data Centre with ADSM and let it up again.
If I don't do that, the tunnel between Site A and Data Centre will NOT resumed.

In Syslog I also se...
