I have a Synology NAS inside my LAN network which does DDNS and it registered the WAN IPv6/IPv4 addresses as its own. From LAN it shows OpenWRT login page.
The issue I am having is that this DDNS whatever.synology.me when accessed from inside LAN should use the local IPv4/IPv6 addresses rather than the WAN. Does anyone have some guidance on 22.03 / nftables - hairpinning or NAT loopback setup instructions?
I know a solution to this problem could be to port forward all synology ports but at this time I only wish to fix the loopback to local IP addresses when traffic originates in LAN segment. I am opening a single port for wireguard to dial back in from WAN for the rest.
