I'm having some trouble getting IPSEC to work through a satellite link. The telco tells me that the link is IPSEC compatable, but cant tell me any specifics for my router. Ive asked them for optimal MTU, MSS, and windowing parameters but they just shrug. I would like to use rbscp but our routers firmware doesnt support it. So can anyone point me to some generic info on getting good performance from satellite links?
