How to Port Forward

Step 1: Log in 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)

Technicolor    admin             admin

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, you will be prompted to enter a custom name for your device. Then you’ll enter the desired port you are forwarding in the port field (default EPSON terminal printer port: 9100). Select “TCP/UDP” under protocol or “Both” if you are unsure of which protocol you are using. Next, enter the internal IP address of the printer you are port forwarding to and click “Apply” or “Save” to store the changes. To get printer internal IP click here: get printer internal IP

Step 5: Finally, check if the port is open by going to www.portchecktool.com. Enter the port number you have forwarded and click Check Your Port. If the port is available, a report should come back stating so.

You should now be able to connect to your printer via a web browser. Enter your hostname followed by the port number into the address bar—for example, http://hostname.ddns.net:9100.
