Perf issues on OpenVPN(and IPsec) with Site to Site

spoonchild

Hey Everyone,

I've been fighting an issue where site to site with two PFSense boxes. My connection is 100/15 and the remote is 50/10Mbps. Connection is established, and working great with the exception that I'm only get about 1Mbps of transfer. No matter what I seem to do it is throttled. I had started with IPsec as well, and it had the same issue. I have another IPsec tunnel and it pulls the full ~15 up I have when transfer on it(connected to Windows Azure). I don't know if it's ISP throttling at this point, but wanted to see if anyone had suggestions. I've searched the forms, and tried doing MSS Clamping, but it did not help on this tunnel. I've turned encryption off to test, but haven't had a chance to try since changing the settings. I don't have a client from off the ISP I can try to see if it's ISP limit or not. Any ideas would be very much appreciated.
