We're trying to offload VPN traffic from our main firewall with a ISG 2000 running 6.3.0r13b.0 which we pulled out of the closet. This is a route-based VPN, but even with a single copy process started to the remote location, cpu spikes over 80% and the copy process is much slower (less than 1/2) of what the main firewall is with all processes running over the tunnel. I'm hoping I missed a setting that might boost VPN performance. Can anyone help me out? Thanks
