whoops - forgot this is a dual homed computer and I am opening the eth0 to the outside world for ssh. I did find this - iptables -A INPUT -p tcp --syn --destination-port 22 -j ACCEPT iptables -A INPUT -p tcp --syn -j DROP this confuses me because of the "DROP" and the "--syn" Thanks, Doug -----Original Message----- From: Simpson, Doug Sent: Tuesday, January 14, 2003 1:59 PM To: 'netfilter@lists.netfilter.org' Subject: ssh I have acomputer I want to ssh to from the internet.
