I am on Mac OS X Server so the command to turn off window scaling is sysctl -w net.inet.tcp.rfc1323=0. I did that and it worked!
Thank you Victor for the suggestion and your patience. And thank you very much Wietse for pointing out that I had not done it! I thought I had done that but it turns out I had set the window scaling factor (net.inet.tcp.win_scale_factor=8) and when it didn't work I dismissed it as an issue. I apologize for not posting the full binary file off-list. I didn't understand the request at the time. I am going to figure out how you read that TCP window scaling was turned on from my output and move on. As Wietse pointed out this may be a firewall issue. I have been shopping for a better router. I have a couple customers a month ask me and all I can tell them is not to buy the one's I've used. This Netgear FVS318g has been a real pain when it comes to using VPN through it. There are no options for letting most VPN protocols through with rules so I was happy to go to DMZ for now since it let me get more of my VPN stuff working. If anyone knows of a decent firewall in the $300 or less range let me know. Regards, Justin T
