How to configure RED50 with one connection to internet and one connection to private WAN?

Greg Dum

We have multiple manufacturing sites within the US, each site has its own T1 for private WAN and its own internet connection as a backup to the T1.  Despite pulling as much traffic out of the private WAN as possible, we have grown out of the T1's (shocker, I know).  Right now the RED50 sits astride the local internet connection while a Cisco router serves the T1.  Default gateway is the layer 3 core switch which has the RED50 as its default gateway and separate static routes called out for the T1.

Can I put the Cisco router and it's associated T1's behind the RED50?  I want to make the site's local internet connection the primary and make the T1 the failover connection or (if possible) do load balancing across the two.  Is anyone else running this configuration?  How do you get there from here since the WAN connection will not be able to reach the provisioning server (no internet on the WAN).  I would assume that since the secondary (WAN) connection can't get to the provisioning server it would never be used.  Any help or experience greatly appreciated--GD

    Hi, Greg, and welcome to the UTM Community!

    "Can I put the Cisco router and it's associated T1's behind the RED50?"

    Yes, but you can't tell the RED 50 to have the T1 connection both behind it and, in essence, in front of it.  I can't "see" your suggested topology, so maybe I've misunderstood your question.

    I would not use a RED 50 for this situation, but an SG 115 with a Network Protection subscription.  That's less expensive than a RED 50 with Warranty Extensions and gives you the flexibility of using QoS and Uplink Balancing with Multipath rules and usage weights for the connections.

    Cheers - Bob
