Hello!
Iptables accept such line without problem:
iptables -t nat -A PREROUTING -p tcp --dport pop3 -j DNAT
--to-destination 1.2.3.4:25
Destination port is defined by word. So i wanted to use use the same
trick in DNAT but i've got:
# iptables -t nat -A PREROUTING -p tcp --dport pop3 -j DNAT
--to-destination 1.2.3.4:smtp
iptables v1.4.12: Port `smtp' not valid
Is it intentional behavior of iptables? I can't see any info about it in
man.
Regards,
Marcin
