      OK, pfSense newbie here… small office is getting a T1 line, either 8 or 6 public IP addresses will be available. Comes in over a managed Cisco 1721 router from AT&T.

      3 machines within the LAN need to be accessible to the outside world via those public IP addresses (serving HTTP/SSH/VoIP). The other 20 or so machines just need to be able to access the internet (NAT is fine I guess?).

      So...
      1. Can pfSense do this? Basically it's just utilizing multiple public WAN IP addresses and forwarding them to a specific LAN address.
      2. Is the the right way to do things? Is there a better way to set things up?
      3. If pfSense can do #1, can I also choose to only allow certain ports (only open up port 80 to the outside world?)
      4. One of these machines is an Asterisk VoIP box... can I QoS that box to give it priority to the T1 connection?
      5. Is a P3 1ghz, 128mb of RAM enough to handle the traffic over a T1?

      • Thanks!

        1: yes
        2: create VIP's for each public IP you have. Use the VIP's in your port forwardings.
        3: NAT and firewall are separate. You create them independant –> yes
        4: Take a look at the Traffic Shaper Forum. I'm not sure if you can shape multiple different IP's. Maybe the new shaper can do that.
        5: That should be adequat.

        We do what we must, because we can.

          128 MB of RAM is the minimum supported.  If you ever plan on adding any packages you'll want to add more RAM.
