![]() ![]() On a 2nd WAN IP address & same internet connection, I have a Cisco RV042 that is adjacent to the Sophos UTM. ![]() ![]() It sure seems like QoS policy or behavior and not firewall, right? > Am I right to conclude that something is happening to my voip packets in the UTM9? Calls to go thru, and quality is better after hours when there's no other load. (And notably, our in-house voip phones, which ride on the same LAN but on a vlan, which go upstream thru an entirely different firewall router, all work fine, no dropped packets.) I don't see dropped packets in the ethernet interfaces anywhere not in my UTM, not in our managed ethernet switches, or in my pc. A capture at the wired client shows high loss in the incoming stream, and good quality outbound. On the LAN side I see high packet loss and poor quality. We don't have any other Traffic Selectors or Bandwidth pools in place.Ī packet capture at the WAN interface (with tcpdump from within UTM9) shows all voip packets arriving & I can play the stream in wireshark, incoming audio is clear, but outbound packet loss is high. I also tried adding two more selectors for inbound (the original two are outbound). I added a bandwidth pool (10 megabits) with the two selectors checked, and I turned ON QoS on the WAN and LAN interfaces. I added two outbound traffic selectors, one for Voip protocols & another for sip, rtsp, and several relevant Collaboration app types. I configured Interfaces / Status for the 100mbit/sec up/down rates. So I thought I'd dive in & try to make Voip calls work, to make sure I understand the QoS features in the UTM9. I also observe poor quality & high packet loss (both directons) for voip calls from a wired sip client (LinPhone & voip service) on my lan. I'm trying to address poor online meeting performance for our users, most recently with Google Hangouts but also with GoToMeeting & others. ![]()
