iptables: -p all AND --dport xx (is it possible)

[Alan :)]

The following rule can't be applied

iptables -A INPUT -p all --dport 80 -j DROP

the above fails stating that --dport is not recognized.

I'm trying to drop all traffic to port 80. If I provide a specific protocol it works. For example: iptables -A INPUT -p tcp --dport 80 -j DROP

any ideas?
