Connecting the Untangle

In order to connect the Untangle to the network:

  • Ensure the modem or other ISP provided equipment is in bridge mode. Anyone familiar with the local network setup will be able to assist with this.
  • Note: If the IP address is static, it will be necessary to load this information into the Untangle.
  • Connect the router to the modem provided by the ISP, ensuring that it is the only device connected. All other devices will connect to the router or a switch connected to the router.
  • In most cases, the router can be accessed locally at 192.168.0.1 or 192.168.1.1.

 

Creating a Bypass Rule

Untangle firewalls use bypass rules to allow traffic to bypass firewall rules, packet inspections, and session timeouts (UDP timeout).

  • From the dashboard navigate to config
  • Once on the config tab navigate to Bypass Rules
