We have a remote site that is changing their subnet. They have an access list doing a NONAT across the VPN tunnel.
Will anything break if we just leave all the crypto maps, and the access lists the same, simply change the IP addresses that are defined from 192.168.x.x to 10.x.x.x, , reapply the config on the remote pix which will break the VPN tunnel, then apply a new config on the PIX we have here? Will the config work OK, after both ends have their subnets changed and then we just send interesting traffic across to bring the tunnel back up? I am pretty sure that it is set up with pre shared keys. what problems will we run into? How can we debug if we have a problem? We have no one on site that can help. Can we do a reload 30 like you can on a router on PIX 6.3? That way if it fails the router will reboot later if we don't do a write.
