Configuring 3rd DSL Modem for Specific Routeon a Sonicwall 3060Pro

Medium Priority
Last Modified: 2013-12-14
I have an office with 3 DSL Modems.  I have a Sonicwall 3060 Enhanced that allows me to Load Balance two of them.  We have alot of RDP connections inbound via VPN so I would like to route all Exchange traffic (RPC over HTTPS) to my Main office via the 3rd DSL line.

I have a 2nd smaller Sonicwall TZ150.  My idea was to connect the 3rd DSL line to the WAN port of the TZ150.  Then firewall everything except HTTPS traffic to and from my home offices Exchange IP.  Then I assigned an IP address to the LAN port of the TZ150 and another to a LAN port on the TZ3060 that was in the same subnet.  Then I setup a route for all traffic going to my exchange server to be routed out the 2nd LAN port of my TZ150.
The thought sounded good but I can get it to work.

So it should go
3060 LAN0X -->3060 LAN1X -->TZ150 LAN0X-->TZ150 WAN-->Internet-->Exchange Server

Thanks in advance
Watch Question

We should try see first where the packets are blocked.  

Are you able to connect to the Exchange Server with this setup anyway, or this traffic is blocked?

Can you post a traceroute to the Exchange server?

Can you post the result of a ping to the Echange Server?  Sometimes, some ICMP messages from a ping can help.
