I am somewhat new to Linux networking and running in to a issue with iptables I am just not making any headway on.

Two notes before I get in too it. iptables is version 1.4.14, and it is a custom embedded server using custom distro of Linux.

The issues I am having is that -j REJECT parameter is unavailable. If I enter something like (as root) "iptables -A INPUT -p tcp --dport 80 -j REJECT" the error "iptables: No chain/target/match by that name." is returned.

If I enter the same thing with -j DROP instead iptables accepts it and works without issue.

So the question is what is missing in my installation that is causing this?

Thanks.

Load the external module with modprobe ipt_REJECT and try again. DROP is in native, but REJECT is optionnal

If it is a custom kernel, you maybe need to add it in the kernel compilation. Check the /boot/config file if it exists.
