Appendix A: Troubleshooting
Common Problems and Solutions
VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Router.
AH has limitations due to occasional incompatibility with the NAT standard.
Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP address and
your local IP address. For example, if your VPN server assigns an IP address 192.168.15.X (X is a number
from 1 to 254) and your local LAN IP address is 192.168.15.X (X is the same number used in the VPN IP
address), the Router will have difficulties routing information to the right location. If you change the Router’s
IP address to 192.168.2.1, that should solve the problem. Change the Router’s IP address through the Basic
Setup tab of the Web-based Utility. If you 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 being 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. Refer to “Problem #9, I need to set up online game hosting or use other Internet applications” for
details. Check the Linksys website at
www.linksys.com
for more information.
8. 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 Web-based Utility. We will be setting up web, ftp, and mail servers.
A. Access the Router’s Web-based Utility by going to
http://192.168.15.1
or the IP address of the Router.
Go to the
Applications & Gaming
=>
Port Range Forwarding
tab.
B. Enter any name you want to use for the Application.
