Cisco 1721 DMZ?

[bartbauldry]

Hello, im currently using a cisco 1721, it has its default fastethernet0 port along with a WIC-1ENET and a WIC-4ESW in the WIC slots.

Im wanting to connect the 1ENET port to a cable modem to my ISP, (this is working ok) and NAT the connection to the 4ESW for my LAN, this seems again to be working ok. The problem i am having is i want to pass the other public IP addresses im assigned from my ISP to the fastethernet0 port to create a DMZ.

Can any one please point me in a direction?

Thanks

Hello
There's 2 way to do this,but it all depends on your present config.(You did post your config so I can't advice on the correct one)First one is to build an identical NAT statement for the DMZ interface.Then map the incoming traffic to the servers behind the DMZ subnet.Second way is to build a NAT pool with the address you want to NAT to the DMZ.Then do the same port forwarding as above.
