Should/how often  do I need to change the PSKs for VPN tunnels.  Why aren't the PSKs encrypted in the configuration   or is this an option?

Thanks

You don't really need to change the PSK's often, dynamic IPSEC keys are used for Phase 2 of the VPN and they are renegotiated every 8 hours default.

Sounds like your config is on a router?

Thanks Andrew, yes this is a site to site VPN between two 2811 routers. Obvoiusly I lack a clear understanding of how the encryption process works in this case, so I don't really understand if I need to afford the PSK the same protection as a secret key
