Multiple IPs on wan

mikeyman · Jul 29, 2008, 2:37 AM

I have a firewall box with 3 nics in it. One is for lan, one is for wan and other is for dmz. I am provisioned to be able to have 2 public ips but they have to be obtained thru DHCP. What I want to do is have one public ip to do nat for my lan and use the other ip for 1:1 nat on the DMZ. I will have my voip adapter on the dmz, and thats it.

The problem is how can I get 2 public ips thru dhcp on the wan? Im pretty sure I will have to change the mac address to get the 2nd ip. Would I have to setup 2 vlans on the wan nic and change the mac address on the 2nd vlan? What are my choices, best options? Thanks!

There isn't currently a way to get a virtual IP via DHCP.

–[ cable modem ] – [hub] – [ pfsense ] –-[ lan switch ]
| /
[ linksys ] /

get a hub or switch, plug your cable modem into it, along with pfsense WAN interface, and a linksys or other router.

this way pfsense would pull a DHCP address from the cable modem, and so would the soho router which would then NAT it to a static internal ip for pfsense to use via opt1

then policy route VOIP to opt1
