Hi all, I am having a peculiar issue here.
Server is getting it's IP address from the router via DHCP, the DNS settings are manually set (208.67.222.222, 1.1.1.1, 8.8.8.8).
It can be pinged from network, it can ping anything in the network, but cannot ping anything outside the network.
Hence it cannot access anything on the internet.
Ping from unraid to router:

I am a little bit at my wits end and not sure how to continue.
I restarted the unraid server and the router, nothing seems to work.
Not sure if it is interesting but I can access the server via the https://<checksum>.unraid.net address.
