Route Extra IPs to Machines

[ANSASERVERS]

Hi Guys,

i am in some desperate need of assistance. Telstra (our carrier) is going to be mirgrating our services across to their new system tommorow and therefore we will have the chance to have more then one ip address. My question is how can we route the ips through PFsence so:

a, snort and other applications that we have on our PFsense box still filter and block the trafficas required
b, the traffic is passed through pf sense and onto the machines so these extra ip addresses DO NOT use NAT. Its a direct connection to the server through PFsense ( if possible )

Pfsense is currently controlling our PPOE sessions and will remain like that. We just need step by step instructions on how to route the ips to the dedicatd macihines on our network. We have the ip gateways, broadcast addresses and subnets that we need but dont know how to route it.

I did read somewhere that you use Nat 1:1 but i carnt see where to enter the IP addresses. It only asks for the subnet which is the same internal and external.

We are using the latest build of PFsense.

Please provide step by step instructions so we can follow and explain every step in as much detail as possible.

Thanks in advance

Matthew

I forgot to add the Pfsense box is a virtual machine on our hypervisor and currently has 2 network cards. One network card is called LAN and the other is WAN.
