Hi guys,

Here is the situation:

We have two company offices in different cities, one with ADSL and one with G703 leased line (one E1 for voice and a second E1 for internet access - but 1Mbps up/down) and both have an IP enabled PBX. We bought two WRT54GL routers for each end and installed Talisman VPN 1.3.7 so that our internal (office-to-office) communication is routed through a VPN tunnel. Can we use QoS of your firmware so that when downloads take place at the same time the voice quality is not degraded?

Is there a guideline or a howto of how to setup this system?

Thank you in advance.

Yes. Enable QoS on each router and enter the actual Uplink and Downlink speeds (you can use something like www.speedtest.net to measure them). Then create a rule for whatever protocols you want to deprioritize and set their action to Bulk. This means these protocols have lower priority than anything else at the default 'Standard' priority whenever bandwidth is used.

Ok this setup is now up and working. I used WAN QoS since everything else crippled the download speed no matter the settings used. Now we need to connect a third router to this VPN and the question is will this VPN work three ways? 1->2, 2->1, 1->3, 3->1, 2->3, 3->2... do we need to setup some routing entries?

thank you in advance,
george.

PS: if this system works reliably we will be using it for future clients

The VPN should be transparent to the router. VPN's normally handle their own routing.

VPN's normally encrypt traffic so the QoS packets will be invisible to the router. You can add a QoS entry for the VPN protocol (I assume it's either IPSec, L2TP, or PPTP) and raise it to Express. You can also add entries for protocols like FTP, P2P, etc and lower their protocol to Bulk.
