Model: Deco XE75  
Hardware Version:
Firmware Version: 1.2.1 Build 20230601 Rel. 58453

Hello,

 

This will be my first post in this forum. I'm out of ideas on how to continue troubleshooting my problem. We have 6 TP-Link Deco XE75 in a mesh network. In this network there is also a Zyxel GS1900-24HP switch that handles 7 network cameras (Dlink DCS-4602 and Dlink DCS-5222L) through POE. All devices, switches, etc. run on the same subnet 192.168.0.x.

 

In XE75 there are rules set up for NAT to the network cameras according to:
Service: Customized
Internal IP: 192.168.0.x
Internal port: 443
External port: 923x
Protocol: TCP

 

The network cameras are each set to respond to https 443 and have an IP range between: 192.168.0.231 - 192.168.0.237. The external port set for NAT corresponds to its camera's IP address, eg: internal IP 192.168.0.231 port 443 -> NAT -> external IP port 9231.

 

If you are on the subnet, you can access all network cameras. However, the network cameras cannot be accessed from the Internet. I have also set up similar NAT rules to access, for example, the Zyxel switch's web interface to test NAT in Deco and that web interface works to be accessed from the Internet.

 

If you start the VPN server in XE75, all devices can be accessed through the tunnel except for the network cameras. The VPN server creates a subnet of 10.0.0.x and it seems to route everything correctly to 192.168.0.x but the network cameras still have no access through the VPN tunnel.

 

We changed the router to the Deco XE75 Mesh, as we previously had an ASUS with NAT rules and then there was no problem accessing the network cameras.

 

Tried to find something in the system logs but can't find anything about the network cameras in particular.

Hi, Thank you very much for the feedback.

I would like to forward your case to the engineers for further assistance. Please check whether you could get an email from me later.

Just to confirm that- "I have also set up similar NAT rules to access, for example, the Zyxel switch's web interface to test NAT in Deco, and that web interface works to be accessed from the Internet." If you have configured a port forwarding rule for Zyxel switch's web interface, you are able to access the web UI from the internet, right?

 

Thanks a lot.

Best regards.

  @David-TP Thank you for your reply and to forward my case!

 

What I meant by the NAT rules for the Zyxel switch was that I checked that NAT worked in TP-link Deco with another local device and then chose the Zyxel switch. There are no NAT rules set up in the Zyxel switch, it is on the same subnet as all other internal devices 192.168.0.x. The Zyxel switch's web interface is then accessible through NAT from the Internet, but not the cameras that are connected with POE through the Zyxel switch. When I run the same test with the VPN (OpenVPN) set up in the TP-Link Deco, the Zyxel switch's web interface is accessible on its local IP address, but not the cameras' local IP addresses.

 

TP-Link Deco: 192.168.0.1
Zyxel GS1900-24HP: 192.168.0.17
Dlink DCS-4602 and Dlink DCS-5222L: 192.168.0.231-192.168.0.237

OpenVPN in TP-Link Deco: 10.0.0.x
