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
If your packet loss problem relates to a third-party firewall, proxy server, and/or an ICMP checking program you are using with the Windows XP Internet Connection Firewall, you may be able to eliminate packet loss. Follow the instructions below to eliminate 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.
