      Thanks for your time. I wanted get your input on the specific traffic shaping schedulers/algorithms that I should consider. I'll outline my goals and then provide an overview of my network.

      Goals

      Primary goal:  Prioritize VOIP traffic. I have a home VOIP line and AT&T microcell. The call quality gets destroyed during heavy internet use. I would expect no more than 4 concurrent users.

      Secondary goal: De-prioritize VPN traffic (although, I am willing to skip this goal if it would over-complicate things).

      My Network

      • Current release of pfSense x64

      • Supermicro SYS-5018A-FTN4 with 16G ECC ram

      • 2x Juniper ex2200, "stacked" in a virtual chassis

      • Comcast, consumer grade internet (130 mbps down, 12 mbps up). Pings to 8.8.8.8 average 20-30ms.

      • Single physical WAN interface, although there are two gateways (one for OpenVPN traffic, and one for everything else)

      • "LAN" side of traffic:

      –--- 4x front-facing interfaces are bundled in LACP to Juniper ex2200 switch

      ----- LACP bundle is a trunk of 7 VLANs; VLANs are given separate "logical" interfaces within pfsense

      ----- One of the VLANs exclusively carries the desired VOIP traffic

      ----- One of the VLANs exclusively carries traffic bound to the OpenVPN tunnel

      Summary

      I would appreciate your input in creating the following:

      High Priority: VLAN with VOIP traffic

      Middle Priority: Regular traffic

      Low Priority: VLAN with OpenVPN traffic [although, we can skip this priority level, if it would over-complicate things]

      Thanks for your time.

      Supermicro SYS-5018A-FTN4 (Atom c2758)
