port-forwarding

Hello,

I want to forward a port from my remote vps to my domestic server and I am quite a newbie with iptables.

The problem is that I am using a dynamic dns service to reach my home server from the internet so I don't have a fixed ip and iptables doesn't like urls.

The rules I am willing to use are these:

-t nat -A PREROUTING -p tcp -i eth0 -d xxx.xxx.xxx.xxx --dport 8888 -j DNAT --to myhome.tld:80
-A FORWARD -p tcp -i eth0 -d myhome.tld --dport 80 -j ACCEPT

Of course I recevie a Error BAD IP ADDRESS because of myhome.tld.

What can I do?
