Problem was solved by me. I entered the wrong HTTP ports and server ports in my App DDNS configuration for cam 2 and cam 3. I accidentally swapped the ports. Now everything works fine as expected.

Only my TP Link router is displayed as connected device in my Netgear extender, s. screenshot.

I definitely have access to all my cams by DynDNS in my web browser.

Hey everybody,

I have three IP cams. I try remote configuration in Hik Connect App for all cams. Only one cam gets configuration access.

I have three Hikvision IP cams connected with an old TP-Link router N600 (TD-W9980B) to its LAN ports. This router is connected by WAN port to LAN port of Netgear Range Extender EX3700. The range extender gets WiFi by Speedport W 925V modem router. This router is connected to internet.

Speedport router

• does not support UPnP
• port forwarding is set for UPnP ports of all cams connected to TP-Link router

TP-Link router

• WAN mode: dynamic ip
• own network with DHCP enabled
• access to internet
• does support UPnP
  • UPnP seems to open ports

IP Cams

• Platform Access: Hik-Connect
• enabled UPnP with manual port mapping

Hik Connect App

• I have set ports in DDNS configuration (HTTP port 280 / server port 28000)

[Speedport router] WiFi -> WiFi [range extender Netgear] LAN port -> WAN port [router TP-Link router] LAN ports 1/2/3 -> see below

-> LAN port [IP cam] IP 192.168.1.101
-> LAN port [IP cam] IP 192.168.1.102
-> LAN port [IP cam] IP 192.168.1.103

Live streams work fine for all cams. DynDNS access by browser works fine.
For one cam with IP 192.168.1.101 I get remote configuration access by Hik Connect App. For IPs 192.168.1.102 and 192.168.1.103 I cannot get any access.
If I disable port forwarding on my Speedport router or if I disable UPnP on my TP-Link router I get no remote configuration access for all cams at all. So these two settings seem to be required.

I attached some screenshots.

Do you have any idea what's wrong?
