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).
