puts this problem into words better in case my email dont make sense. Portion of article below: ***Unavoidable half-second delays as signals bounce off the satellites can wreak havoc with IP Security because it takes so long for TCP acknowledgement to get back to the sending machine. TCP interprets the satellite delay as network congestion and throttles back its sending rate, meaning the IPSec VPN traffic gets through but at a much slower rate than the link could actually support.For non-VPN traffic satellite providers get around this problem by spoofing the acknowledgements using devices that are placed between the satellite base station and the customer's sending machine. TCP on the sending machine perceives no congestion and sends at the fastest rate the satellite link can bear.*** Hello All, I have a remote location that I have had a satellite installed at by Skycasters. The internet connection i get with this is great by itself with bandwidth around 600 - 700k ( we paid extra for better connection) . Well the whole reason for this connection was to run vpn over it but as soon as we put a vpn firewall or software solution on this connection we get about a 56k connection. Of course skycasters now says oh you want to run vpn? it will cost an extra 1400 bucks and and additional XX.00 amount per month and we will hook you up with SUPER VPN! here is what they say on their site. ----------------------------------- ......Due to the Asymmetric nature of satellite internet, certain applications do not perform very well over satellite, regardless of whether used in a VPN, SuperVPN or in the clear. SuperVPN is not a not a cure-all for satellite-related performance issues, it simply is a way to use VPN without the traditional severe VPN-induced degradation. It does not increase whatever level or speed of service that would be available for a particular protocol/application above the level found if the application/protocol were to be used "in the clear"............. ------------------------------- I am hoping someone with simular experience with vpn connection can shed some light on this and tell me if i can do anything myself with router configs , software solutions etc. etc. to handle this problem. ANY and ALL replies will be greatly appreciated!! Thank you, JD
