Wan2: 60Mb
Wan3: 75Mb witch 1 public IP
I loadbalance 3 wan.
Internal network I have 2 subnet.
1 subnet for LAN (172.16.0.0/16)
1 subnet for wifi (172.15.0.0/16)
I have 1 web server in LAN (IP web server: 172.16.254.3)
I want to public web server by NAT port forarding. I NAT via Wan1.

But, user inside not ok. when I access my website in internal network, My website redirect to WebGUI pfsense.
I can not access to my website.

Either enable a NAT Reflection mode or configure split DNS to resolve its domain to is LAN IP address.

Sorry, let me ask you the question the other day
I used pfsense 2.3.5. I setup pfsense on PC with 5 Lan card.
I setup 3 WAN ppoe on pfsense.
wan1: 100Mb with 1 public IP
Wan2: 60Mb
Wan3: 75Mb witch 1 public IP
I loadbalance 3 wan.
Internal network I have 2 subnet.
1 subnet for LAN (172.16.0.0/16)
1 subnet for WIFI (172.15.0.0/16)
I have 1 web server in LAN (IP web server: 172.16.254.3)
I want to public web server by NAT port forarding. I NAT via Wan1.
when I NAT web server, user outside access my website is ok.
But, user inside not ok. when I access my website in internal network, My website redirect to WebGUI pfsense.
I can not access to my website.

Then I followed this direction:
Either enable a NAT Reflection mode or configure split DNS to resolve its domain to is LAN IP address.

https://doc.pfsense.org/index.php/Why_can't_I_access_forwarded_ports_on_my_WAN_IP_from_my_LAN/OPTx_networks

I check that ok
But today I found out that

It's only ok when I access my website by WIFI interface.
When I access my website by LAN interface not ok.

WIFI interface: 172.15.0.0/16
LAN interface: 172.16.0.0/16
Local IP my website: 172.16.254.3

Please help me.

Why would you use such large masks??  Makes no sense to use such a large mask that includes 65K possible address.  Do you have that many hosts that might connect to those networks?

Thanks you.
everything was ok when I switch to mode NAT + Proxy
Originally I chose the mode Pure NAT

Thank so much
