Port Forwarding Issue: WiFi WAN to VLAN with Incorrect Source IP

[Ouahid]

I have a Peplink MAX BR1 Pro 5G, and I’m experiencing an issue with forwarding packets from the WiFi WAN (10.42.0.92/24) to VLAN 4 (192.168.4.1/24). After configuring port forwarding in the WiFi WAN to a server at 192.168.4.10 in VLAN 4 for a single port, I noticed that the packets are being forwarded to the server, but the source IP address is not the LAN port address (192.168.4.1); instead, it’s the source address of the client on the WiFi network (10.42.0.93).

I would like to know how to configure the Peplink router to use the LAN port (192.168.4.1) as the source IP address when forwarding packets from the WiFi WAN, and reverse the process for traffic in the other direction. Could you please help me resolve this issue?

How to Configure One-to-One NAT Mappings

NAT Mappings also known as 1-to-1 NAT allows internal hosts, such as web server and mail server etc., behind Peplink Balance to communicate to the Internet via all protocols. With 1-to-1 NAT, you can: For inbound traffic, forwarding all TCP/UDP/IP protocols to the host behind the Peplink units. For outbound traffic, you can specify a Public IP address which you defined as "Additional Public IP" via WAN Settings as the source IP address. The followings are two scenarios of configuring 1-to-1…
