Configuring Port Forwarding with Multiple IP Addresses
Internet Connection: Cox Cable Business, 5 Static IP Addresses (no access to the cable modem gui)
Cabling: Cable from Cox cable modem to PFSense box, cable from PFSense box to switch
Goal: To be able to use all 5 IPs with 5 servers I have behind PFsense (3 web servers, 1 sql server, 1 mail server)
I've spent all day googling, reading forum posts, and trying to configure PFsense without any luck. This question has been addressed on a per-case basis, but there doesn't seem to be a guide for it.
Currently I have one IP configured in the wan interface and 4 virtual IPs set in Firewall > Virtual IP Addresses. I've tried IP Alias and Carp configurations without any success.
I've read the documentation for Virtual IP types at:
Does anybody know of a step by step guide for this?
The closest I've found is:
Do I need to have access to the cable modem's gui to configure anything?
Any help would really be appreciated.
You can use the 1:1 NAT function for this.
I've added the physical cabling/wiring info to my original post.
Nat 1:1 won't work for me as I want to direct different ports to different IPs. IE: IP 1 goes to webserver 1, IP 2 goes to webserver 2, IP 1 & IP 2 go to same smtp server. All servers are on an internal network (10.x.x.x.)
Can you tell what is your wan address from pfsense. NOTE THAT I DON'T WANT ACTUALLY KNOW THE NUMBERS. just is it RFC1918 address or is it public.
Then you can add Proxy ARP addresses and then you can select them when creating a NAT rule (Firewall: NAT: Port Forward) under "Destination Address"
