Firewalling IP/subnet mask (or IP range)???

I tried applying this guide to my router by blocking the specified IPs/Ports on the firewall page. But it doesn't seem to have had any impact.

Does anyone know the best way to block these IPs?

Edit:

This IPs I want to block are:
173.194.55.0/24
206.111.0.0/16

The problem I'm having is that I don't know how to block the entire range of IPs, since there isn't an option to enter a subnet mask on the firewall. Does anyone know of a script I can have the router run to block these two IP ranges?

Any ideas?

You can block by this rules:

iptables -A INPUT -s 173.194.55.0/24 -j DROP
iptables -A OUTPUT -s 173.194.55.0/24 -j DROP
iptables -A FORWARD -s 173.194.55.0/24 -j DROP 
iptables -A INPUT -s 206.111.0.0/16 -j DROP
iptables -A OUTPUT -s 206.111.0.0/16 -j DROP
iptables -A FORWARD -s 206.111.0.0/16 -j DROP

Is there any tutorials on how to enter these commands. I asume they are done using telnet. New to all this router tweaking.

Hi Andy,

Well, you need to go thru the learning curve:
- Your router runs a stripped down version of Linux: So the basics of Linux usage/management/configuration need to be understood.
- To make the iptables settings permanent you should use the Merlin firmware with the possibility to add user scripts, which will be executed on each reboot of the router: You should to flash the latest Merlin firmware - need to learn how to do this.

But: First of all you have a good forum here, where you can find the things you need by searching it and then asking specific questions.
And: You can google for the Linux basics...

Merlin is very active in this forum (user RMerlin) and any issues/topics related to his firmware will be answered very fast - or even fixed in his firmware.

Finally: You will learn something new, which is always fun!

With kind regards
