Network traffic routing plays key role in your network, if you have single site with heavy browsing or multiple sites, replicating important application data from your Primary Default Gateway ,you have to route your other network traffic from your primary gateway to secondary gateway.

This article will step through configuring  static routes in your SonicWALL Network Appliance to route HTTP /  HTTPS or any specific traffic to Secondary Default Gateway. This article applies all SonicWALL Network Appliance supporting Sonicwall Enhance OS.

This article assumes that you have Two (2) ISP, and both connected to your Sonicwall Appliance via ISP Modem/Router.
 
NOTE: It is assumed that both WAN connection are configured and active.

HTTP Rule :
Login to the SonicWALL Network Appliance and go to Network >Routing > Add (refer to Figure 1) >
Source:      LAN Subnet or Any
Destination:       Any
Service:       HTTP
Gateway:       Secondary Default Gateway
Interface:       X2
Metric:       20
Comment:       HTTP Route

(Optional) Select the Disable route when the interface is disconnected checkbox to have the route automatically disabled when the interface is disconnected. i Recomend to CHECK this BOX.

(Optional) The Allow VPN path to take precedence.I Recomend to leave this box UN-CHECKED.

HTTPS Rule :
Login to the SonicWALL Network Appliance and go to Network >Routing > Add (refer to Figure 2) >
Source:      LAN Subnet or Any
Destination:       Any
Service:       HTTPS
Gateway:       Secondary Default Gateway
Interface:       X2
Metric:       20
Comment:       HTTPS Route

Once both rules created you can also verify, logon to your SonicWALL Network Appliance> Network >Routing. you will be able to see new created rules (refer to Figure 3)

You can create as many rules as you want, if you have two or three ISP  i would strongly suggest you to route trraffic on Multiple ISP. Custom routes can also be created for IT staff Downloading or Uploading Data.
