My Asus router (flashed with Merlin firmware) connects to my ISP router via static IP because my ISP blocks their router config, so I cannot put it on bridge mode.
I also have NAT on because I do not trust my ISP’s router security.
Since I needed to create a VPN server, I had to call my ISP to ask them to open ports for it. They opened two ports (let’s say 7777 and 7778, these are not the real ones by the way) and gave me a public IP for my clients to connect. But there is a catch, the ports are only available to the device with the assigned IP 192.168.15.254 in their router LAN.
So, I went to WAN and set the static IP to 192.168.15.254. This way I can create a VPN server in my Asus router and my clients can connect using the public IP provided by the ISP.
My Asus router uses DHCP and the LAN IP is 192.168.1.0, all my devices connect to my Asus Router.
The problem is that if I create the OpenVPN server on my PC behind my router (let’s give it the IP 192.168.1.200) my VPN clients cannot connect to it.
How can I route the incoming connections to my PC running the VPN server?
Here is what I’ve also enabled in my Asus router:
Port forwarding:
What else am I missing? Sorry if it is something simple or a stupid question, I’m mostly self-taught using internet tutorials and the good old “trial and error”.
I never had issues creating OpenVPN servers on my LAN devices with my older ISP (I could set their router to bridge mode), but my current ISP is the only one serving fiber where I live.
I even tried messing with static routes in the WAN config, but I don’t fully understand how they work, and my attempts amounted to nothing.

Here is what I’ve also enabled in my Asus router:
Port forwarding:
- External Port / Internal Port = 7777
- Internal IP Address = 192.168.1.200
- Protocol = Both
- Source IP = blank
- PPTP, L2TP, IPSec passthrough are all enabled
- RTSP, H.323 and SIP passthrough are all enabled + NAT helper
