A little more information is needed. Is this a gateway to the internet,
say using eth2? If so then you need

iptables -t nat -A POSTROUTING -o eth2 -j MASQUERADE

also

echo 1 > /proc/sys/net/ipv4/ip_forward

You'll probably want to add the following line to /etc/sysctl.conf
net.ipv4.ip_forward = 1
So you don't have to enter the above echo command each time you restart
your system.

If this is just a bridge between two subnets, you probably don't need to
change your NAT table. I haven't set up a bridge myself, so I'll let
someone else talk you through this, but I expect you will only need to
adjust your routing table.

thanks got it to work editing the sysctl
