How do I stop my camera trying to access 192.168.252.2 ?

[scottydj2]

Hi,

I have an Annke I51DW camera set up and working fine with BI. It is on an isloated 192.168.16.xx vlan on my network.
Every 5 minutes my firewall blocks it trying to access 192.168.252.2
I can't seem to find a way to stop this call.
Anyone provide any further info?

Thanks,

Scott

For starters, I'd log into the cam's webGUI and insure that P2P and uPNP are disabled.
Is there a device on the LAN with that IP?

Hi Tony,
From the webGUI I have pretty much everything disabled already.
I don't use a .252 subnet on my lan, and can't see anything with that address.
Thanks,
Scott

Any chance you set that address as the cameras default gateway?

Hi Fenderman,
No, it gets its IPv4 details from the DHCP server and has correct .16 subnet gateway and DNS details.
Maybe I'll need to get a wireshark trace to dig a bit deeper.
Thanks,
Scott

It's on a 24port POE Unify switch with a Unify Dream Machine Pro gateway if that makes any difference.

It's probably trying to find a default gateway out. What did you set as the gateway? If blank, you might try setting it to the cam's own IP. That may help keep things out of your logs at least. Or it might not if it's hard-coded to try to find a gateway when it can't. Same with DNS servers. Some will try Google's at 8.8.8.8 and 8.8.4.4 if blank or it can't find a valid DNS.

That's very interesting...
So camera is looking for a default gateway to the internet?
At the moment, external access to the internet IS allowed via the normal .16.1 gateway, I'm just not allowing connection to anything within my own networks.

Hi Mike,
As mentioned above, the gateway and DNS are filled in, and connections out to the internet are not (yet) disabled. This does work, as I can use an internet NTP server successfully. It's only being caught by my firewall as the 192.168.252 subnet is being treated as an 'internal' network, and hence blocked.
Thanks,
