Can I configure a UTM 9 with 2 wan interfaces on different IP addresses with 2 different LAN network interfaces at the same time. in effect, have 1 UTM filtering traffic on 2 separate WAN's and 2 separate LAN's?

Can I configure a UTM 9 with 2 wan interfaces on different IP addresses with 2 different LAN network interfaces at the same time.  in effect, have 1 UTM filtering traffic on 2 separate WAN's and 2 separate LAN's?

Can I simply create a additional WAN interface with its interface IP's along with an additional LAN port with its separate IP and keep the 2 networks divided via VLAN on my switch ?  I dont want the 2 different local networks crossing over.

 

What would be the procedures and best practice for accomplishing this ?

 

Thanks in advance for your help

  • Yes you can do that, however remember that once you use web filtering in the UTM that by default over the proxy every network connected to the UTM can communicate with every other network connected to it. When using web filtering you need to make exclusions for this.

    Also you need to add in some rules to specify which LAN should use which WAN and whether or not the other WAN interface can be used in case of a WAN outage.

  • Hi Drew and welcome to the UTM Community!

    If you want to restrict traffic for each VLAN to a specific WAN connection, see How to change the outgoing interface for Web Filtering.

    Also, you might be interested in a document I maintain that I make available to members of the UTM Community, "Configure HTTP Proxy for a Network of Guests."  If you would like me to send you this document, PM me your email address. I also maintain a version auf Deutsch initially translated by fellow member hallowach when he and I did a major revision in 2013.
