Interesting... why would it be dropping smtp and not any of the others, like ftp?This one time, at band camp, David P James said:
I sshed to my brother's Redhat server and did the telnet my.host.ip 25 thing back to my server; the connection timed out. I tried a few other ports (21, 80, 22, 110) and got a connection quite quickly.
Then apparently iptables is DROPping connections to that port - fix that and we'll move from there.
I just want to make sure I don't go nuts opening things up willy-nilly here; this is what I was thinking of having looked at a multitude of firewall scripts online:
# iptables -A INPUT -i eth1 -p tcp -d 24.x.y.z --destination-port 25 -j ACCEPT
# iptables -A OUTPUT -o eth1 -p tcp -d 24.x.y.z --destination-port 25 -j ACCEPT
where eth1 is the external interface.
