Firewall/NAT

Hi,

My ISP hands out 4 WAN-IP addresses (if I hook up 4 physical devices onto my cable-modem).
I already tried to put my VOIP Router, another router and the monowall onto a switch to the cable modem, which just works fine (I get 3 public addresses...) - but my question lies in another range.

Would it be possible to make one WAN port on monowall, receive 4 (or multiple) IP addresses by DHCP... I would suspect the router has to impersonate 4 different MAC addresses on this one NIC, but I don't know if it could be possible, and if so, how should one make this work?

This would make it pretty easy to add some devices in a 1:1 NAT (eg. Playstation3)
Now my PS3 tells me that the device is in NAT Type 3, which would limit some of the capabilities (didn't test it though)

Kind regards,

You can only get one IP from m0n0wall's DHCP client (and every other firewall and DHCP client I've ever seen).

You can use a bridged setup to pull the public IPs directly to the clients.

Reviving an older thread, but... I've got the same setup from my ISP (RCN Cable Internet) as mservaes does.

I can get the bridged solution working just fine. However, I am trying to set up a home network with IPs dedicated to multiple PCs which I would like to live on the same network. The suggestion made by cmb puts the 'other' computers on Internet IPs instead of my 192.168.0.X network.

I can get around this using virtual interfaces or multiple NIC's on each PC with a dedicated IP, but I would much rather have m0n0wall bridge the extra IPs to the PCs at 192.168.0.2 and 192.168.0.3 directly. Can bridges (or interfaces) be configured to do this?

[EDIT] 3 IPs distributed as follows:

Existing Setup:

Modem -> m0n0wall interface A
m0n0wall interface B -> WAN IP 1 on NAT for switch & wireless access point (192.168.0.X DHCP)
m0n0wall interface C -> switch
switch -> WAN IP 2 for PC 2 (using WAN IP)
switch -> WAN IP 3 for PC 3 (using WAN IP)

Desired Setup:

Modem -> m0n0wall interface A
m0n0wall interface B -> WAN IP 1 on NAT for switch & wireless access point (192.168.0.X DHCP)
m0n0wall interface C -> switch
switch -> WAN IP 2 on 1:1 NAT for PC 2 (192.168.0.2)
switch -> WAN IP 3 on 1:1 NAT for PC 3 (192.168.0.3)
