Routing public IP's through a gateway

Hi all,

I have a bit of a complicated question.

I have two ethernet devices, eth1 and eth2.

eth1 is where my internet comes from. It is in the form of 202.172.122.208/29.
It has another IP range, 202.172.122.72/29. What I want to be able to do is
route 202.172.122.72/29 to eth2, so that other machines (My Users) can use those IPs,
any ideas on how to do this, I cannot work out how to do this.

Detail: ISP —eth1(202.172.122.208/29)— MT —eth2— Public IP users
| — Private IP users

2 ip blocks given by my ISP. 202.172.122.208/29 and 202.172.122.72/29

Note: I also have some private ip users (NATed).

Chap.
