Hello,

first of all this is the the netfilter developing mailing list, maybe
you try the users mailing list next time?? ;-)

What you want to do can easily be done with the REDIRECT
target. Try something like

iptables -t nat -A PREROUTING -p udp --dport 78 -j REDIRECT --to-ports 98

Hope this helps ;-)

Sven
