Quick question on Dahua port forwards

[rt050 0]

Hi there,

 

I have a quick question regarding port forwarding for a Dahua DVR.

 

I have set-up port forwarding for users to view the CCTV on their mobiles and forwarding the corresponding ports.

 

However, I was thinking the other day and wanted to set-up so I can view remotely via a browser too.

 

So I forwarded external port 37777 to internal port 80 to the DVR unit. So via WAN I can get as far as the login page but it then gives me a message 'Login Failed'.

 

I'm assuming this is a security issue.

 

So a few details, I have a static IP reservation for the DVR set on the firewall so no internal IP conflicts. I can access the DVR internally on the network and via mobile phone app just not externally via web browser.

 

So far I have forwarded ports -

 

External 37777 (tcp) - internal port 80 on 192.168.1.11

External 37778 (udp) - internal port 80 on 192.168.1.1

External 37777 (tcp) - internal 37777 on 192.168.1.1

External 37778 (udp) - internal 37778 on 192.168.1.11

External 554 (tcp & udp) - internal 554 on 192.168.1.11

External 161 (tcp) - internal 161 on 192.168.1.11

External 443 - internal 443 on 192.168.1.11

 

Is this correct? I can't for the life of me work out what I'm doing wrong here!

 

I have another DVR on the network, via completely seperate ports (alien dvr) and forwarded it to it's internal ip on port 80 and it works fine. But a completely different system I gues.

 

Any ideas??

 

Thanks in advance!!

Change web port on the Dahua from 80 to 90 so it will not conflict with your other DVR, and forward the following ports:

 

90 -> 192.168.1.11 90 (TCP and UDP)

554 -> 192.168.1.11 554 (TCP and UDP)

37777 -> 192.168.1.11 37777 (TCP and UDP)

37778 -> 192.168.1.11 37778 (TCP and UDP)

 

And when you want to access the device from internet use:

dont use port 80 change to 8080. also each port should be both. Ur problem is u need to use the external IP address yo view ur cameras remotely. not the address 192.168.1.whatever. plug ur laptop into ur router and goto WHAT IS MY IP ADDRESS. put that number onto ur phone ipad etc and the port. the 192.168.1. whatever is ur LAN. that's what u want to view on ur desktop http://192.168.0.1:3777
