As I posted, the DVR works fine when connected to the old system but not when connected to the new one and a separate profile for the DVR was created for the new feed. We even saved the old config and wiped the router, so only one profile existed and that still doesn't work. The settings were saved and printed, so they could be set up the same way, but with the new IP address. The DVR's ddns search was successful, but after the port forward setup, canyouseeme.org was unable to see it.
Is the IP assigned to your router the same as the one the DVR is registering with your DDNS provider? Have you attempted connecting the DVR directly to the provider’s Ethernet handoff (if it’s even feasible)? That would isolate whether your issue is upstream or on your router.
