I have this setup in my small company:
There are three devices:
Huawei LTE router - 192.168.100.254
Cisco RV180 router - WAN 192.168.100.101, LAN 192.168.2.1
Netgear Switch - 192.168.2.2
Huawei is only providing the internet connection, has Firewall disabled and DMZ set up for ip 192.168.100.101. This works and I can remotely connect to RV180 online management console. RV180 management is set up to work only on https with a custom port, so port 80 should be free. In Cisco I have set up another DMZ, this time for ip 192.168.2.2. However, I can not access Switch management remotely from WAN on port 80. What might be the issue?
(I know this should be done by port forwarding, but it didn't work anyway so I decided to start with DMZ.)
