Sorry, late contribution for your consideration: Incase you do not suceed, try this. On your router ETH int, create a sub interface and gateway it to either Sat or kenstream. Since WAN ports are on different subnets already ( Sat / Kenstrem ) , point main eth gateway to kenstream and sub int to satellite. Put in a static route so that LAN network can see the other ( though it will show as directly connected ? )Then change either network clients TCP gateway to point to the respective router gateway. Me thinks .....HTHs.  :-)
