Where do we put IPtable rules should be added?

[edit] Save iptables

Can we please get info on how to save iptables so they are restored on reboot? Thanks --Shibz 09:30, 23 Jan 2007 (CET)


I think dd-wrt stores the config using nvram, which doesn't seem to store formats for custom iptables commands.

  1. nvram get forward_spec

SSH:on:both:22>x.x.x.x:22 HTTP:on:both:8080>x.x.x.x:80 FTP:on:both:21>x.x.x.x:21

It seems like you should enter custom iptables commands in the http interface by accessing Administration -> Commands -> Save Firewall

There is a nice example iptables script for a different purpose here: [1] --Urule99 04:17, 1 August 2007 (CEST)

[edit] ddwrt chains

I think is interesting add information about DD-WRT specific chains and rules.

For example, what about "mangle" table with QoS services configured.

[edit] iptables order of operations

Looking at the comment "Sorry but don't you think this code will be better to run ? [DROP at the end] ", since those are using insert mode, I believe the rules will be pushed on to the top of that table, and will be executed in reverse order. I think the user's comments would be correct if the command was in append mode, but in insert mode I believe they have confused script order with chain execution order.
