How can I do 1:1 NAT with just 1 Static IP
I'm new here and I tried searching about my question but I couldn't find whether it has been posted before. If this has already been posted, I'm truly sorry for asking a duplicate question. My problem is simple. I just have 1 static IP from my ISP. I wanted to do 1:1 NAT of that address to the internal mail server. How can I do it in pfSense? Thanks in advance for your answers.
Why want you do that?
There is no advantage of 1:1 NAT with only one IP.
If you do this you can't neither access any local services on pfSense nor access web configurator from internet. So I would prefer port forwarding.
However, it will be doable if you really want that. Just go to Firewall > NAT > 1:1 and add a new rule. Enter your public IP at External subnet IP and enter your internal servers IP as single host below.
Thanks for your answer. So it will be better to forward the ports required by my mail server.

Do you have as well a DHCP available to you from your ISP?
If so you could create a VIP for the static and then 1:1 it to your desired server. Otherwise as said- just port forward your mail ports. :)
