Is there a PIX that supports rebooting a single Site-to-Site VPN? Right now we are currently using a WatchGuard, but when one VPN fails to renegotiate the key we have to reboot all the IPSEC tunnels (only option). We hate to do this incase it knocks someone else off. Is there a PIX or VPN Concentrator that allows us to reboot a single tunnel instead of all of them?
