Jim,
InterPacket Networks offer IP/DVB services to our 650 customers in
over 100 countries.
The logistics of allowing each customer to put a firewall of their
own at the satellite head end are problematic to say the least.
Please appreciate that we push many many customers traffic onto the
satellite carriers using our diverse upstream connectivity. There is
no single point on our network we could pick off just your traffic
and filter it.
Its like asking UUnet to put a firewall in their core just for you, forget it.
How much bandwidth are you looking for via satellite?
