Port forward using extrenal DNS from the LAN

[johnw230873]

Hi, I have a simple external DNS domain set up and in opnsense I have some simple port forward rules set up.

I then have some application on my phone that use these port forward rules. They work fine on the public network (e.g. coming in on the WAN) but when I'm on the LAN they don't seem to reverse back in to the LAN network.

Any idea what I could be doing wrong here.

Firewall -> Settings -> Advanced -> Network Address Translation
Check All 3:
Reflection for port forwards
Reflection for 1:1
Automatic outbound NAT for Reflection

NOTE: It probably will not work if you are using web proxy (Transparent or explicit). I am facing issue when using web proxy on opnsense. So test it first without web proxy enabled..
