Hi, 
I have two Dahua DVR in LAN network. Both DVR work correct in LAN with Smart PSS 
and Android gDMSS application. For outside connecting I'm set port forward  
on my router. For one DVR default 37777 and second on 37776 port. From Smart PSS 
app everything work correct but for Android gDMSS only work DVR on default port 
37777. I try to change different port, different app (Pegaso HD lite) but same  
situation. What is correctly settings for port forwarding? Am I wrong in some  
settings?  
Any information that you can give me would be helpful. 
Thank you
