I created a firewall using ipchains and it seems to working well. However, I am rejecting packets every so often that are completely a mystery to me. These are output packets on my external interface. They are sourced from my machine and destined to my ISP's DNS server. They are being sent and received on port 3 and are using PROTO=1. What the hell is protocol 1 and why would my system want to send these packets on port 3 to my ISP's DNS server???

Do you log those packets? Could you provide the full line from /var/log/messages? Really port THREE?!!??? -- Michael Hasenstein http://www.suse.de/~mha/ SuSE Linux AG, Nuernberg (Germany) SuSE Inc., Oakland, California (US) -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/support/faq
