I have the following requirement:

I have a block of 10 public IP address and need to use two of those.
I need a ADSL/Firewall device that woud allow to direct traffic (HTTP and HTTPs) to two different servers in my private network, each server is on a different subnet.
This is an exmaple of what I need:
Public: 82.xxx.xxx.122 natting to private
Public: 82.xxx.xxx.123 natting to private

Currently I have a Xizel 660 router set in nat mode.
The Zyxel is connected to a Watchguard 10e firewall
All the traffic is directed to

Can anyone suggest a device that will help me route external traffic to two different internal subnets?

Are  you saying you can only set up a single nat in your current router?

Almost any router you choose will let you nat each of your public ip's to a private IP.

At home I'm using a Cisco WRVS4400N, it can do this.

You need to set your router to bridged mode Ths is the key step
Give the WAN interface on the watchguard an External IP one up from the router
Add all your external IPs to the WAN interface as secondary IPs

Give LAN 0 an ip in the range
Give LAN 1 an ip in the range

Then  create a 1 to 1 NAT on the watchguard

82.xxx.xxx.122 natting to private
82.xxx.xxx.123 natting to private

If you are not useing firmware version 11.3.2 then upgrade and use h Watchguard System Manager to configure your device it is much easier to use than the Webinterface

thnk you, this has pointed me in the right direction. The latest firmware version for my warchguard does pretty much what I need along the lines you suggested.
