Nebula Overlay network and Outbound NAT configuration

[Brodiecyber]

Hello

Ive been using pfsense for a while now with openvpn as my what if remote access.
im busy experimenting with overlay networks like the product from slack known as nebula for a mesh solution. i have a nebula client behind the pfsense appliance now the nebula client can ping out to my roaming client but it cannot ping in through the firewall i read that this is a known issue with opensense and a workaround is detailed in the blog post. i know it has something to do with UDP port randomization with pfsense.

Ive tried to replicate the rules configuration but to no avail the issue is still persists. Does anybody have an idea
