Troubleshooting

A

assigned a static IP address to any computer or network device on the network, you need to change its IP address accordingly to 192.168.2.Y (Y represents any number from 1 to 254). Note that each IP address must be unique within the network.

Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec server.

I need to set up a server behind my router.

To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed. Follow these steps to set up port forwarding through the router’s configuration utility. We need to set up web, ftp, and mail servers.

STEP 1 Access the router’s configuration utility by going to http://192.168.1.1 or the IP address of the router. Go to Firewall > Single Port Forwarding.

STEP 2

Select the Service from the Application column.

 

 

STEP 3

Enter the IP Address of the server that you want the Internet users to access. For

 

example, if the web server’s Ethernet adapter IP address is 192.168.1.100, you

 

would enter 100 in the field provided. Then check the Enable box for the entry.
