-
Hi, what is best practice for LAN and WAN ports to keep open. I don't use any NAS or local servers inside. Just browsing and emails and use OpenVPN as client. Do I need to keep open ports 53, 123. 853 for LAN or WAN?Please any tips? I keep open for this moment LAN ports: 80, 443, 587, 993, 465, 1195, 123, 53, 853 but in doubt regarding ports 53 and 853 and 123. Do need to keep open this ports on LAN or WAN?I'm using unbound as local resolver with pfBlockerNG .,no any forwarding and just a few domains override resolving for Cloudflare!
