and it works well.
two things are important:
- make sure nat'ing works (iptables -A POSTROUTING -t nat -j MASQUERADE -s  
192.168.0.0/24)
- bear in mind that /etc/resolv.conf of the om does not necessarily allow  
name resolution. it contains only 192.168.0.200 as nameserver which  
usually will not work. add the ip of your router (if it does name  
resolution) or any other nameserver (from your host's resolv.conf) and  
remember that every reboot of the om resets the resolv.conf
