- | fwbuilder works with files created using ''iptables-save'' - which is '''NOT''' part of DD-WRT. | ||
- | If you download the ipkg iptables-utils which contains iptables-save & iptables-restore, you will find they do not work, and give you error messages such as these : | ||
- | |||
- | /jffs # iptables-save | ||
- | # Generated by iptables-save v1.3.3 on Wed May 14 09:04:13 2008 | ||
- | *nat | ||
- | :PREROUTING ACCEPT [1791:460202] | ||
- | :POSTROUTING ACCEPT [9:1323] | ||
- | :OUTPUT ACCEPT [103:16861] | ||
- | '''Can't find library for match `tcp'''' | ||
- | -A PREROUTING -d 82.36.194.23 -p tcp /jffs/etc/iptables # | ||
- | |||
- | However, V24 of DD-WRT ''has'' been modified to support iptables - although the iptables-save command is not present - however you ''can'' get it to work :) | ||
- | |||
- | '''Instructions :''' | ||
- | # Enable [[Journalling Flash File System]] | ||
- | # Run the following | ||
- | |||
- | cd /jffs/usr/bin | ||
- | ln -s /usr/sbin/iptables ./iptables-save | ||
- | cd /jffs | ||
- | iptables-save > iptables.txt | ||
- | |||
- | You should now have a file called '''iptables.txt''' containing your firewall rules, which can you then use with fwbuilder :) | ||
- | |||
- | |||
- | I found the above did not work but the following did... | ||
- | |||
- | cd /jffs/usr/bin | ||
- | ln -s /usr/sbin/iptables ./iptables-save | ||
- | ./iptables-save > /jffs/iptables.txt |

Firewall Builder is a GUI for easily creating iptables rules. These are my comments
You can get Firewall Builder (fwbuilder) at: http://www.fwbuilder.org.
Prequisites: You need sshd enabled on your DD-WRT software.
