So there's no consistency here, my guess as I think I've seen it before is technically when the device perhaps doesn't have the correct "gateway" configured or a gateway configured period it seems to not respond to connectivity over the VPN? Would something like that make sense?
More detail;
Have a remote site, with a bunch of IP Cameras configured by a previous vendor. I can access a good portion of the cameras over the VPN for configuration updates. However random sporadic ones (IE not a range / block, but random ones throughout) do not respond to remote VPN access.
It's an IPSec VPN for remote user access.
So I'm wondering if for some reason if perhaps they configured a static IP on the device, but didn't fill in the gateway info / skipped it, perhaps those ones are the ones not working? Is there anything else I could try remotely to troubleshoot. I do have full management access so if you want me to pull any specific config areas.
The ones I am able to access I confirmed they do indeed have the correct static gateway (mikrotik router) configured manually, unfortunately to check the other ones I assume I have to go on site. Unless there's a way I can manually force a route or something?
