I'm using a Procurve 5406zl (J8697A) layer 3 switch with multiple vlans:

**VLANs:**
10 Main Network 10.1.4.1
12 Wireless 10.1.8.1
13 Restricted Wireless 10.0.0.1
14 Tech 192.168.7.1
50 Internet 192.168.10.254

**And Untangle with 3 nics:**

External (Uverse)
Internal (LAN)
Primary IP: 192.168.10.1 /24
IP Aliases:
10.1.4.0 /22
10.1.8.0 /22
10.1.12.0 /22
192.168.7.0 /24
10.0.0.0 /20
DMZ (DSL Connection, this connection we're doing away with)
eth3 (New fiber connection)

**And Static Routes:**

Target: 10.1.4.0 - Gateway: 192.168.10.254
Target: 10.1.8.0- Gateway: 192.168.10.254
Target: 192.168.7.0 - Gateway: 192.168.10.254
Target: 10.0.0.0 - Gateway: 192.168.10.254

**Changes I'm looking to make:**

I'd like to start utilizing the new fiber connection added to eth3 interface.

I'd like to have all of the VLANs to start using the eth3 it except for VLAN 13 which is our public wifi id like for it to continue to use the "External" interface.

What do I need to do in order to start utilizing this new connection on eth3?
