I have a 5 site network setup with 5x ISA550Ws. Two sites have a static IP address (site A and site B) which the other three (site C, D, & E) access via site-to-site VPN.
In a matter of a few days after a new FW update is released (not yet installed), all sites lose their connections to the static sites minus the connection between sites A & B. I am forced to visit each site, do the FW upgrade (A & B first) and manually reconnect sites C, D, & E to A & B. This also causes any AnyConnect connections to A & B to fail until a reboot is performed on those two devices.
A---------B
X X X
C D E
(excuse my poor excuse for a diagram)
Is this some sort of standard behavior or is there something I'm missing? (outside of putting static IPs on the other three sites)
