How can I forward ports with pfSense?

From PFSenseDocs

1. Go to the Firewall menu, select NAT, click on the Port Forward tab.
2. Click on the + (plus) icon at the bottom of the screen.
3. In the page that should now be displaying, enter your forwarded port in the External Port range box(es), enter the internal IP address you'd like to send that port to.
4. Then check the "Auto-add a firewall rule" checkbox.
5. Click 'save' which will return you to the Port Forward NAT screen, showing you all the NAT entries.
6. Finally, click 'apply' - wait a few seconds and test.
