Testing DNS Redirect code snippet

Hi Shaun,

this is already done automatically while hitting Save.

I’ll just add a few screenshots to demonstrate:

  1. The patched optionsfw.cgi looks like this. I added DNS, NTP-switches. And: options for BLUE are only shown if BLUE exists:

01_optionsfw.cgi

  1. These switches (should!) add a few REDIRECT rules - or delete them, if they exist - in the CUSTOMPREROUTING chain:

02_NAT_rules
02_NAT_rules748×226 5.54 KB

  1. The adding - or deleting - of these rules has to be done with the command /etc/rc.d/init.d/firewall restart - and I like to trigger this through an added Save and Restart button at the end of optionsfw.cgi:

03_save_and_restart
03_save_and_restart905×135 3.29 KB

So when hitting Save not only the page settings are saved - as before - but additionally the firewall settings should be restarted “for changes to take effect”…

And because its the same procedure as before - plus a “few” tuning measures - the usual message appears after choosing Save And Restart:

04_changed_restarted

Note that I changed the Force DNS on GREEN option.

But the CUSTOMPREROUTING chain isn’t changed, the rules for GREEN are still there:

05_NAT_rules

And I’d like to avoid a complete reboot…

Doing exactly the same through a root console with executing /usr/local/bin/optionsfwctrl restart - a newly added program - works.
