I recently setup a FortiGate 70D as the firewall/router at our office. We are able to connect to the VPN, but the throughput is incredibly slow. We have a 100/100 fibre connection, but all VPN traffic (remote clients are mostly on OSX or IOS) runs under 5Mbps.
I don't think I have any traffic shaping going on, CPU load looks reasonable, I have adjusted encryption types, local clients get our full port speed (mostly, upload can be sluggish it seems but always 20Mbps+).
We are running firmware v5.2.4,build688 and have experienced the slow speed with different remote ISP's. We replaced an old SonicWall and we did not have this same sluggishness in the old setup.
Any troubleshooting advice would be greatly appreciated!
Just an update, I have done some reworking on the network and I have our old SonicWall hooked up on a different WAN IP to compare. I have tried to match protocols as best I can, but the FortiGate VPN (Both SSL and IPSEC) is still dramatically slower than the other VPN.
My next step is to wipe clean the VPN Configuration and try starting from scratch, but if I am to do that does someone have a guide that covers the steps? I think I needed to hybrid two guides the last time and that could be causing my problem.
Any thoughts or insights would be appreciated.
