This is commonly referred to as router mode. Also, If you have tagged VLANs it is much simpler to run Untangle as a endpoint of those VLANs. This also places it in a convenient place to handle other seperate internal networks (like wireless segments) that may only be connected at the gateway.

It is usually the simplest approach and it allows Untangle to leverage its full feature set including WAN Failover and WAN Balancer. Installing Untangle as the gateway/firewall is recommended.
UNTANGLE FIREWALL MAIL SERVER INSTALL
Install Untangle behind an existing gateway/firewall in flow with traffic.Install Untangle as the gateway/firewall for the network.Obviously, Untangle must be installed in-line with all network traffic so this provides two options: The first step, after understanding the above cardinal rules, is to decide where to place Untangle on the network.
UNTANGLE FIREWALL MAIL SERVER HOW TO
For Untangle to operate correctly, you must configure Untangle with a complete routing table so it knows how to reach all hosts on your network. If you have a subnet that Untangle doesn't have a route for, then it will be sent to the default gateway even if that subnet is internal. This is often a surprise to people on complex networks as effectively you will need to tell Untangle where to send all the traffic on your network if you want it to go to the correct place. Traffic passing between bridged interfaces are still subject to this cardinal rule. In the Untangle context, two bridged interfaces share a configuration (some products call them "zones"). Where Untangle differs is that Untangle is often installed as a bridge or with some interfaces bridged together. They receive packets on an interface and then lookup in the routing table/rules where to send it. Obviously, this is how all routers operate. Untangle routes ALL traffic according to its routing table. Without a valid internet connection and configuration many functions of Untangle will not work properly. This includes unfiltered HTTPS, HTTP, and DNS access to various cloud services. Untangle must have a working and consistent connection with the internet. Untangle and many Untangle apps rely on cloud services. Untangle MUST have a working internet connection.
All applications and functionality are designed to operate in a context where Untangle is installed in-line with the network flow of traffic. It is does not operate as a explicit proxy that you "point" clients' browsers to send web traffic. Web Filter will filter web traffic as it passes through Untangle. It will not store-and-forward to your email server like some products. This isn't how Untangle is designed and it will likely not work.įor example, Spam Blocker will filter SMTP as it passes through Untangle. Some network administrators want to deploy some of the functionality of Untangle without installing Untangle in-line. Untangle is a gateway product, and it is designed to be in-line with network traffic. Untangle routes ALL traffic according to its routing table.Untangle MUST have a working internet connection.There are several key rules to how Untangle operates that should be understood before deploying Untangle in an advanced/complex network. This describes how networking operates and is configured in Untangle. However, some networks have multiple WANs, multiple LANs, various subnets, VLANs, VRRP, etc. For simple, networks the configuration completed during the Setup Wizard is probably sufficient. The most critical configuration in Untangle is the proper configuration of your network settings in Config > Network. 1.7.4.5 Is state shared between Untangles?.1.7.4.4 How quickly does traffic switch?.1.7.4.3 How can I test my VRRP configuration?.1.7.4.2 How can I see which is the VRRP master?.1.7.4.1 What kind of problems count as a failure for VRRP purposes?.1.6.1 Configuring VLAN on Untangle in Bridge Mode.1.5.2 NAT traffic coming from this interface (and bridged peers).1.5.1 NAT traffic exiting this interface (and bridged peers).
