Site2Site IP Routing - splitting data & voice

[afrogley]

First off I know this probably isn't the best place - but it's one of the most active and u guys may well have done similar!

Background:
IP Office 406v2 (on 4.2.4) in main office.
Draytek Vigor ADSL Modem/Router with WAN2 capability.

13 IP phones at remote site
Draytek Vigor ADSL Modem/Router with WAN2 capability.

Currently 1 Site2Site VPN.

Scenario:
I'm setting up 2 dedicated ADSL connections for voice traffic - 1 at each site. My intention is to join them via a second site2site VPN.
The IP Phones at the remote site will be DHCP'd but will be on the same subnet as the PCs (intending to use the built in switch so I can just plug the current computers through the back of them)
Rather than have a second gateway at each site, I thought I may be able to use the Draytek Vigor routers to control the traffic route & VPNs - voice traffic down WAN1 and data traffic down WAN2.
Or have I not quite worked this out right?

Best to use two vlan's, one for voice and one for the Pc's/data you can still use the port of the handset for the PC's and still issue addresses by DHCP. But it will seperate broadcast traffic, make routing easier and allows Qos to be configured and it isn't much more work

Ah .. yes VLans ... time to find out how they work then!!

and I don't think I can use the Draytek units to control both Site2Site VPNs as they'll get confused... but I think I know a way around that ...


Ta!

on the draytek 2820's latest firmware you can do policy based routing.

e.g, UDP traffic via WAN1, TCP via WAN2

also, you can apply static routes to send specific traffic out via different WAN / LAN ports.

I would check this out rather than VLANs, because the draytek probably doesnt know what to do with the VLAN Tags TBH.

Hi HSM - upgraded the firmware to 3.3.4_232201 (on a 2820) can't find the policy based routing part ...

Static routing is ok - but not sure how that will work as I had hoped to have the phones on the same subnet ...

with your static routes, just make very specific routes then

rather routing a subnet, route the specific IP via a specific gateway.

Ok - ta ... I looked at both of those - but didn't think of the specific IP routing ... shouldn't be too hard!
