Outbound Packet Loss

Enable Lost Packet Recovery: Lets the system use Lost Packet Recovery (LPR) if packet loss occurs. so you'll need to make sure that is not blocked. You can try to fix this by forcing the primary NIC on the system to the one you want to use for your traffic, but generally, windows will still choose shortest route, which in VLAN's etc can cause the system to send out the traffic, but then not be able to get there. In normal cases packets are not lost, so the source assumes congestion has occurred when timeout happens. I've ruled out it is my VMware setup, as I have an Ubuntu box running on the same VM host that the Sophos UTM is running on. It seems that my server is running smoothly. Packet loss could be due to a failure or an inefficiency of a component that carries data across a network, such as a faulty router, a loose cable connection or a bad wifi signal. This has been happening on and off for the last week or so, but today it has been at a constant 20-30% packet loss only on the outgoing. It was the ping timeout setting. Some WANs have low latency and no loss and are great, others perform normally even when there is some loss registered on the line or higher latency.

In the command below, we can see that everything is working fine – there’s 0% packet loss and the time each packet takes is fairly low. 015MB and having the same issues. When packet for a second new session from the same lan host within the timeout period matches this rule, it will use the same wan interface as the first packet and the timeout counter is reset back to 300 again. The solution to this problem is our Managed Hosted Voice Service. Calls to or from mobile handsets (cell phones) will often drop simply because the signal on the mobile handset was lost. The counter names themselves although called "dropped" (or "loss" in iMC) do not mean the packet(s) have necessarily been discarded and are generally no cause for concern unless data is actually being lost between ingress and egress. traffic-policy test outbound # 2.
