Windows XP Internet Connection Firewall

Quick Contents

Introduction

Windows XP has an integrated Internet Connection Firewall. This firewall does not directly conflict with your PC Access® for Windows TCP-Telnet sessions.

However, if you use a third-party firewall, proxy server, and/or an ICMP checking program, you will probably experience Internet connection problems. These third-party programs may cause your Internet connection to experience a high volume of packet loss.

• Note: some users run an ICMP checking program to keep their Internet connection alive while they use the Windows XP Internet Connection Firewall.

Correcting Packet Loss

• Note: MFM does not provide technical support for firewall and proxy server programs. If you need assistance setting up or working with your firewall or proxy server program, you need to contact technical support for your firewall or proxy server program.

1. Click Start | Control Panel | Network Connections.
2. In the Network Connections window, right-click on the Local Area Connection icon and click Properties.
3. In the Local Area Connection Properties window click on the Advanced tab. Select Protect my computer and network by limiting or preventing access to this computer from the Internet to enable Windows XP firewall.
4. Click the Settings button (towards the bottom of the window) to open the Advanced Settings window. Click on the ICMP tab and select Allow incoming echo request.
5. Click OK | OK to return to the Network Connections window.
