you generally have to perform this configuration yourself, so you should know if you need UDP\53 opened.Īnother exception is of course if you are forwarding port 80 or 443 inbound to a webserver for public consumption.Īnother potential exception is devices in the home that use UPNP to forward 80/443 to themselves. Depending on your router and its configuration (whether or not masquerading is configured, and whether the router is configured as DNS server for the LAN, or you have another server running forwarding), you may need to have an open port for DNS traffic on UDP\53. Most routers ship with management only available on the LAN interface.ĭNS may be a little different. It is a common best practice to restrict management services to the LAN, or if you need remote, to allow only the specific remote address that will be connecting.
