Tailscale on pFSense: Using exit but not getting home public IP

I have enabled my pFsense to be an exit node

And activated it in Tailscale

My pFsense public IP is X.X.X.X but when I connect my remote client (mobile phone) to Tailscale and call whatismyip.com. it return the public IP of my mobile connection and not X.X.X.X.

What else do I need to do to make it look like my remote client is connecting from my home IP?

Ignore, I worked it out; did not realise I had to explicitly tell client which exit mode to use.
