WAN pass through?

For educational purposes I have my hands on a Watchguard T30 FW but I don’t want to ruin my pfsense config :smiley: How would u configure pfsense to set a spare physical port as some kind of fake WAN connection ?
I know that Lawrence does that a lot. If someone could point me to right video, I would be really grateful.


Just double NAT, put one firewall behind the other.

Working fantastic ! Thanks… For everything :wink:
