[Leaplist] Openvpn over satellite

[tony_l_turner at yahoo.com]

Hi all, am new to the list. I've been using Linux for a couple of years but am definitely still a newbie. 

I'm looking for a good full featured *.nix firewall distribution like IPCop, M0n0wall, Pfsense, Smoothwall, Untangle etc that does a good job of managing TCP window sizes/buffers for high latency connections like satellite connectivity. Configuration might be sat2sat or sat2land. I need a package that works well with OpenVPN as I need to do a point2point SSL VPN to better utilize PEP (IPSEC sucks in this regard)

While it might be obvious that I have a list of solutions already, I either want to find something running on kernel 2.6 or newer to take advantage of new TCP congestion control features not found in 2.4 and older or find a way to load the appropriate module I need to manage high latency connections. I do not currently have a budget for this project but have a couple of spare Dell P4 boxes I can use and a box of network cards. 

Does anyone have experience with this or have any resources you could recommend so I could research this myself? I've been through the previous products FAQs and countless Google searches and found good theoretical info but very little practical guidance. Thanks in advance
