@BlueSun ok, I'm generally out of my depth in regards to BGP. All I can say if you set a gateway in the interface settings (see screenshot) then pfSense creates NAT rules automatically, if outbound NAT is set to automatic or hybrid. [image: 1755188790365-screenshot-2025-08-14-at-18.25.56.png] But since you have disable outbound NAT I can't see your traffic being NAT-ted at all. Are you using the FRR packages and if yes did you have a look at pfSense Docu: BGP Example Configuraton for a start?
