On 2.4.x kernel, use the 'iptables' command :

iptables -t nat -A PREROUTING -d 0.0.0.0/0 -p tcp --dport 443 -i eth0 -j
DNAT --to-destination 192.168.0.10

where eth0 is your public input interface (maybe ppp+ for ppp connexion),
and 192.168.0.10 is your internal server

Use 'iptable -t nat -L' to see your current NAT rules

Have a look at http://www.netfilter.org for full information.
