[. . . ] I am not getting an IP address on the Internet with my Internet connection. · Refer to "Problem #2, I want to test my Internet connection" to verify that you have connectivity. Contact your ISP to see if your Internet connection type is RFC 1483 Bridged, RFC 1483 Routed, RFC 2516 PPPoE, or RFC 2364 PPPoA. Please refer to the Setup section of "Chapter 5: Configuring the Gateway" for details on Internet connection settings. Make sure the cable connecting from your Gateway's ADSL port is connected to the wall jack of the ADSL service line. Verify that the Status page of the Gateway's web-based utility shows a valid IP address from your ISP. Check the Status tab of the Gateway's web-based utility to see if you get an IP address. I am not able to access the Setup page of the Gateway's web-based utility. · Refer to "Problem #2, I want to test my Internet connection" to verify that your computer is properly connected to the Gateway. Refer to "Appendix D: Finding the MAC Address and IP address for Your Ethernet Adapter" to verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS. Set a static IP address on your system; refer to "Problem #1: I need to set a static IP address. " Appendix A: Troubleshooting Common Problems and Solutions 47 Wireless-G ADSL Gateway 3. Refer to "Problem #10: I need to remove the proxy settings or the dial-up pop-up window (for PPPoE users). " 5. I can't get my Virtual Private Network (VPN) working through the Gateway. Access the Gateway's web interface by going to http://192. 168. 1. 1 or the IP address of the Gateway, and go to the Security tab. Make sure you have IPsec passthrough and/or PPTP pass-through enabled. · VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will work fine. At least one IPSec session will work through the Gateway; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs. · VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Gateway. AH has limitations due to occasional incompatibility with the NAT standard. · Change the IP address for the Gateway 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. 1. X (X is a number from 1 to 254) and your local LAN IP address is 192. 168. 1. X (X is the same number used in the VPN IP address), the Gateway will have difficulties routing information to the right location. If you change the Gateway's IP address to 192. 168. 2. 1, that should solve the problem. [. . . ] This equipment cannot be used on telephone company provided coin service.
