Hi,
first do:
echo 'ip_forward=yes' > /etc/network/options
as root. this turns on ip forwarding. This allow packects to be
sent to the next computer and beyond.
My info says that 192.168.1.100 can only send to a host on its
network -- any thing 192.168.1.x. But you set the default
gateway to 10.20.x.x which it can not get to.
Also, I ususally add a '-host' entry to the routing table.
so,
'route add default gw 192.168.1.1'
fixes the route on host1
then on the gateway1 machine:
'route add default gw 10.20.4.48'
to help packets go to gateway2 if needed.
(and of course do the ip_forward thing)
