Hello. This is my first post at Wilders, but have read your forum regularly for three years, and learned much from past and present posters. Many thanks. Been running CHX-I 2.8.2 on a dial-up connection for a long while without a single glitch. Over time I evolved a nice port blocking rule set. A few days ago, I switched to DSL with a modem/router box that has a built-in SPI firewall. After the switch, I lost my DSL connectivity on every reboot. Tracked it down to CHX-I. With CHX-I unistalled and running only only the XP SP2 FW, all is ok. So I reinstalled CHX-I with only the IDRCI work station sample set, and turned on all the CHX-I SPI. As soon as CHX-I is reinstalled, the connectivity problems reappear, sometimes without even a re-boot. The only way to get back the connection is to uninstall CHX-I. The old dial-up connection is deleted, so only the Local Area Connection shows under Network Connections as LAN or High-Speed Internet. Also, to start fresh with DSL, I did a complete re-install of Windows XP and fully updated it. I registered CHX-I with IDRCI, so install it with a life-time free key, not the trial version. I am running PG free & Spyware Terminator HIPS, but do not think they are involved. As a practical user, and not a computer hobbyist, it will be easy for you to get beyond my skill level quite quickly. Any thoughts on correcting my problem would be welcomed. Thanks again.
