Unable to access feeds on separate subnet

[sunkid]

Hi,

I have a new install on Centos 7 and have ZM working fine as long as I keep the cameras on the same subnet (10.0.2.1/24) as the ZM server. When I move them to a separate subnet (10.0.4.1/24), I can still discover them using the ONVIF method and I can view the feeds using VLC. ZM, however, no longer shows the feeds and there are numerous socket and encoding-related errors in the logs.

Adding a NIC to the ZM server is definitely a possibility, but I am trying to understand why that would be necessary.

Any pointers would be greatly appreciated!

Basic networking. Suggest you ask Google... Not a Zoneminder issue

Thanks for the response. Any explanation why it works with VLC but not with ZM?

ZM might be using UDP and VLC using TCP. The camera could be setting the TTL (time to live) with UDP to 1 which would mean UDP is only available on the same subnet.

Thanks all. I solved the issue by adding the NIC for the subnet. Now, I cannot see the cameras in the ONVIF detector, but if I add them manually, everything works.

You could have added a second IP to the NIC if the second subnet was on the same physical LAN. I use Webmin to set this up several times where I want to isolate the cameras by IP from prying eyes on the LAN. I use a second NIC on a system where the ZM server needs to be accessible from separate LANs in the same building.
