Changing DHCP settings from console?
« on: March 29, 2019, 08:50:58 pm »
I've made a mistake configuring a new firewall: I enabled DHCP on LAN and after connecting to the web interface I checked "Deny unknown clients" without immediately adding any hosts to the static mapping list. I didn't realize the problem at first, it only became apparent when my host tried to renew DHCP. I can still log in via the console, but I can't reach the web interface at all. Is there a config file I can edit to disable "Deny unknown clients" for the LAN interface?

I've tried setting "denyunknown" in /conf/config.xml to 0 and rebooting, but this didn't do the trick.

EDIT: Disaster averted! For anyone reading this thread in the future, just follow these steps to save yourself:

  • Log into the firewall console as root or some other admin user.
  • If you logged in as root, hit 8 to go to the shell.
  • Edit the file /conf/config.xml
  • Go to the section <dhcp> and find the subsection <lan>
  • Add the line <enable>1</enable> just underneath <lan>
  • Remove the entire line <denyunknown>1</denyunknown>, don't just set it to 0!
  • Save the file
  • Reload DHCP; if you are logged in as root just go back to the console and hit 11 to reload all services
