Hello, I'm setting up iptables policies on one of my machines and I'm having some problems with it... For a mail server, I set up the following rules:
iptables -P INPUT DROP iptables -A -i eth0 -p tcp -d localhost --destination-port smtp -j ACCEPT iptables -A -i eth0 -p udp -d localhost --destination-port smtp -j ACCEPT iptables -A -i eth0 -p tcp -d localhost --destination-port pop3 -j ACCEPT iptables -A -i eth0 -p udp -d localhost --destination-port pop3 -j ACCEPT iptables -A -i eth0 -p tcp -d localhost --destination-port ssh -j ACCEPT iptables -A -i eth0 -p tcp -d localhost --destination-port 1024: -j ACCEPT iptables -P OUTPUT ACCEPT when checking mail, I can get through but sending and receiving takes an extremely long time... Also (a side note), for some reason I can still subvert the firewall using sftp (port 115)... I have no idea why. _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
