How to assign public IPv4 Subnet to OPT?

Speedy059

Hi Everyone,

I'm trying to do the following on the pfSense box:

Create VLAN 100 (Done)
Add public IPv4 subnet 74.221.216.192/27 to the VLAN 100. Host the /27 gateway (74.221.216.193) on the pfSense, and send all traffic to the uplink/WAN.
Add a DHCP for the 74.221.216.192/27 range to hand out IP's to the OPT port on the pfSense.

Currently, the network is like this:

ISP (4.28.81.69) <–> Switch (4.28.81.70) <--> pfSense (74.221.222.58) ------> Use the OPT port with public ips, and route it to the switch which is routed to the ISP.

Our ISP has static routed a couple /24's to use, and I have made a smaller /27 out of one of them that I want to use on the pfSense and assign it to the OPT port doing the steps listed above. The Switch has a static route of 0.0.0.0/0 to the ISP 4.28.81.69.

what does the switches route have to do with anything?

So are these /24 routed to you via transit?? I this public IP 74.221.222.58 so these other /24's are routed to that IP.. Not attached?

If that is case then just put the /?? whatever you want to subnet them to on your opt - you sure wouldn't be setting a gateway on that interface. And yeah it will go out your.. Just make sure you disable natting of that interface since you have not use for it.
