I have an IPSEC tunnel established between two sites that are within 30ft of each other (the buildings are next door). Both sites get 100Mbps down / 10 Mbps up. I setup an IPSEC tunnel between both sites using the default configuration of DefaultHeadOffice and DefaultBranchOffice in the IPSEC settings. I have policies allowing LAN to VPN and VPN to LAN. Everything is all pretty basic.
Once I setup the tunnel, I tried to do a simple file transfer of one 20MB file between a branch workstation and a server at Head Office. It transferred the file at a speed of 0.7Mbps. Considering both sites get 10Mbps upload, and given some overhead for the VPN tunnel, I would expect the speeds to be at least 7 or 8 Mbps, not 0.7.... Does anyone else have any experiences of insanely slow site-to-site IPSEC tunnels or have any recommendations?
The Head Office has an XG125 and remote office has an XG105 running MR2. Both are at 50% memory usage and between 0-10% CPU usage.
