With OpenVPN, you should not be seeing that big of a drop, with the real limiting factor being the CPU time available for it. You can easily check top and see if that is the case. If you get 45-50MBps between the two locations with out VPN, baring any firewall issues at either end, it is likely a configuration issue in regards to the networking of the machines in question or the VPN software or a CPU resource issue. One of the first areas I would check is the MTU being used on the network interfaces, figure out what the max MTU for the path is, and make sure the VPN software is not sending packets larger than that. You may also want to take a look at tuning(7). _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
