ello everyone.
I have some questions about connection from external network.
I prepared a picture which describe my problem.
Here it is.
1.Ping from my laptop to NVR(any of three) : connection O.K.
2.Ping from my laptop to cctv(192.168.1.12) : not connection
3.Ping from NVR1 to cctv(192.168.1.12) : connection O.K.
4.Ping from my laptop to another device (192.168.2.11) : connection O.K.
5.Of course, all of this device work properly
6.Each NVR records their CCTVs fine.
7.All cctv’s setting is same.
To make up for it, 192.168.2.11 is the only device that can be connected. The other 8 devices refuse to connect.
Each CCTV seems to be unable to accept connections from external networks. BUT....If this is due to the router's port-specific setup differences, how is the connection to the NVRs(and 192.168.2.11) possible?
Sorry for my poor English.
Thank you.
