Hi frog,
I don't know the configuration on your satellite provider but some of them
already use a form of TCP acceleration/spoofing.
If your satellite provider has implemented any form of TCP acceleration this
will have an impact on auto peering and how TCP acceleration works on your
WAN accelerator. Riverbed recommends to disable the satellite TCP
acceleration on the satellite side to get it working on Riverbed.
What I've used alos and helped is HighSpeed TCP, this is helpfull on lossy
environmet like satellite.
WAN Accelerators are using SYN options for autodiscovery process and some
firewalls (PIX is one of them) drop the packet that has the modified SYN
options, this maybe one of the reasons why some sites won't open.
