If you have a router at home or at your office and you wish to reach a device on the network, you will need to forward ports in order for outside traffic to get into your network.
如果您在家或辦公室有路由器，並且希望訪問網絡上的設備，則需要轉發端口以使外部流量進入您的網絡。

Step 1: Login to your router via the default gateway address.

Step 2: Enter the credentials for your router on its login page.
Please Note: The credentials for your router should be found on a sticker located underneath or behind your router. If not, you can try the most common credentials below.

Device         Username      Password
--------------- ---------------- ------------------
D-Link          admin              (leave blank)
Netgear        admin              password
Linksys         admin              admin
Asus             admin              admin
DrayTek        admin              admin
ZyXel            admin              1234
TP-Link         admin             admin
TRENDnet     admin             admin
Belkin            admin             (leave blank)

Step 3: Next, locate the port forwarding settings. Typically this will be under Advanced and then Port Forwarding or Virtual Server.

Step 4: On the Port Forwarding page

Step 5: Finally, check to see if the port is open by going to www.portchecktool.com.
