Host appears to be blocked, but nothing shows that it should be.

I have a RS1221+ with a weird issue. When i connect to my home network via VPN, i cannot web browse or ssh to my NAS. I have another NAS on the same network that I can talk to just fine. After I reboot the NAS with the issue, I can get pings and ssh in for a VERY brief time before it blocks everything again from this one host. I have the firewall off, I have turned off autoblcok (and the allow/block lists are empty anyway), and I have even added the IP addresses of the VPN in the allow list, but nothing seems to help. Is there anything else I can look at to figure out why things are being blocked?

Update: I changed the IP address on the VPN and that also looks to be blocked, so it looks to be the whole subnet that the WireGuard VPN is on. And once again, i verifeid my other Synology NAS responds just fine, so it has to be something on the RS1221+ that is blocking all traffic, including ping, ssh, and web.

Welcome to the forum.

Can we start with an explanation of your VPN implementation (in as much detail as possible) to begin with, so we can get the idea of the setup? Let us know what protocol is in question, as well as the client OS and VPN clients as well.

Also, is this behaviour happening from multiple end clients or a particular one?
