Hi guys, I'm hoping someone can help me with this. I can access my NVR with no problems when on my local wifi network. I have an Asus ac68u router, I have set up the ddns OK, I have set up the VPN ( I think OK,- I can access my router login page and a printer on my local network, from mobile data OK), Followed Randy OpenVPN guide. router and phone say connected. But I can't access my Dahua NVR, I am thinking it is something to do with how NVR is blocked from internet? Or have I set up VPN incorrectly? I have tried just Block from network map area. I have tried Block time(All) in parental controls. This router is new to me, so I would really appreciate it if someone with the same router could be kind enough to explain their set-up / Firewall rules ?
