How to get traffic from VLAN out of second WAN link
« on: February 07, 2014, 03:07:44 PM »
Hi all,

Currently have a Nortel 5540 routing switch which is configured with various VLANs and a few amongst those VLANs are tagged and also configured on a Nortel WSS 2360:

Data (2) - Main corp LAN
WLAN (800) - Access Points
Guest (801) - guest wireless access

The WSS and WAPs service both the Corp wifi and the guest wifi.

IP routing is enabled on the VLANs on the routing switch and the VLANs have an IP address defined on each of them.

There is a default route on the routing switch that sends all traffic out of our sole WAN (internet) connection.

We are going to be getting a second WAN (internet) link and I want to be able to send the Guest traffic out of this link. I have a Cisco 1841, which I will configure an interface with a public IP and another one with a private IP in the Guest VLAN range, will setup NAT and relevant routes etc.

My query is, how can I get my guest traffic to go out the 2nd link?? Is there anyway to have a default route for the corp traffic (the current default route) and a default route for the guest traffic going out the new link?

Or would I just need a route from the guest range to the private IP on the 1841's interface??
The WSS Guest VLAN is configured as the DHCP server for guest clients with routing switch guest VLAN IP address as the default gateway.


Look forward to any responses.
Cheers,
Steve

I have done this a few times.
All you need to do is extend the guest vlan to the Controller and make sure that vlan can be extended from the controller to the Cisco 1800.
when I have accomplished this I made the guest vlan totally flat within the local lan and wireless and left the gateway on the edge router.  As long as guest clients get a DHCP address for the cisco 1800 it will work just fine.

Agreed.  That's how we do it as well.

Thanks for the replies. Glad it can be done.

Can I ask a dumb question...what do you mean by the Controller?

The VLAN is configured on both the routing switch and WSS currently

the controller is appliance that manages your access points.
for you it would be your 2360.
