Im having problems at my brothers place, who lives out in the country and has internet via wireless bridge AP on his roof connected to a good Asus router in his office . I installed a Dahua NVR system awhile back and just can’t seem to get the p2p on the idmss app to connect. It says device is offline but in the Nvr under network easy4ip it says online. I can access cameras on the app via lan ip/domain. I’ve installed many of these systems and never had this issue yet. Hoping someone can help me out. I’m thinking it may be the Outdoor AP from the Internet company blocking it? Also The Ring Alarm system notifications work fine when they are not home.
