I'm not sure I've the picture completely clear (an ASCII scheme would
help); however, in my past experiences with satellite-based
connections, you have to make sure to disable the rp_filter on the
satellite interface:
echo 0 > /proc/sys/net/ipv4/conf/`your sat interface`/rp_filter
To see if this is necessary, try to:
echo 1 > /proc/sys/net/ipv4/conf/`your sat interface`/log_martians
and check your logs (on stock debian systems "martian" packets should
be logged in auth.log, I think). If you see and martian packets being
blocked, I suggest you try to disable rp_filter on the sat interface.
By the way, what's your satellite provider?
