NAT doesn't seem to work
-
Hi,
I currently have issues with a DVR not accessible from the WAN.
The situation is as follows:- pfSense box has public IP on WAN interface
- LAN has 192.168.20.x as LAN
- DVR has 192.168.20.3 as IP
I have forwarded port 81, with automatic rule generation.
When I perform a online port scan, on port 81, I get a positive result that port 81 is listening.When I try to access the DVR from the web, on port 81 (web viewer), the browser just keeps hanging on "connecting…" until it times out (tested multiple browsers)
When I telnet to port 81 of the WAN IP, I get connection, and after 2x enter I get a "bad request" so the DVR seems to be listening properly and not "getting" my request.That strange thing is, the LAN where the DVR is connected, has an IPSEC connection to a branch office. Through the VPN, on IP address 192.168.20.3:81 in the browser, I do get the login screen for the DVR.
Currently I am our of options. The only thing is, the DVR isn't managed by myself, so I don't know the network settings such as the gateway.
It should be good (I guess) since a port scanner and a telnet DO work properly.Anyone has some suggestions?
Edit:
In addition, another device on the same subnet works fine with NAT port forwarding.. That device is listening on port 3201, and is accessible from the WAN IP:3201 in the internet browser. Just to make sure before I call the guy that manages the DVR, I want to run this by you.
The guy that should check the DVR through the web interface stated that everything was working fine yesterday though with the DVR.

I just have tested from another location.
There I do get the web interface for the DVR..From multiple connections I cannot reach the DVR, and from some locations I can…
Someone has any ideas?
