Hi,

I think you're missing forwarding of ESTABLISHED,RELATED between
192.168.1.0/24 and 192.168.10.0/24. Try to change above rules to:

-A FORWARD -s 192.168.1.0/24 -d 192.168.10.0/24 -i eth1 -o eth1 -j ACCEPT 
-A FORWARD -s 192.168.10.0/24 -d 192.168.1.0/24 -i eth1 -o eth1 -j ACCEPT

Best regards,
Marek
