iptables REDIRECT --to-ports range

Asked by ravenpl in Linux Network Security, Linux Networking

Tags: iptables, redirect

I have this rule
iptables -t nat -A PREROUTING -p tcp -d 1.2.3.4 --dport 1234 -j REDIRECT --to-ports 12345-12347

There's actually two Qs
- it suppose to redirect connections to 3 different ports 12345 12347 12347, however my serwer seems to ignore the last port 12347 - no connection is redirected there. Any ideas?
- if new connections arrives, how is determined destination port for this new connection? round-robin, least-occupied, firt-that-connects, etc. ?
