Routing Public IPs on pfSense 6100

Networking & Firewalls
1

Hi all, happy Halloween!

I’m having a hard time understanding how to route specific public IP addresses from a multiple wan block on pfSense.

I have an SG-6100 with 3 WAN connections, each with 5 public IPs. I have customers that pay for a static IP address to be allocated to them and have either all or specific traffic routed through that address to internal system. It’s a multi customer site to which some just use the internet provided with no public IPs required.

I have the VIPs added on pfSense, and each customer has their own VLAN interface. Can anyone help me out as I am coming to the end of this project and need to get it working, whist also understanding how it works.

Here is the write up from Netgate on setting that up

Thanks Tom. I did try to follow that but ended up with no internet at all.

My provider gives me the public IPs in a block so

.160 netip
.161 gwip
.162 pfsense
.163 public
.164 public
.165 public
.166 public
.167 broadcast

Mask of .248

So setting the wan as a /31 doesn’t work and as a /30 doesn’t either.

I’m having trouble with the math today, but isn’t that a /29 or /28?

edit, this says /29 Subnet Mask Cheat Sheet
