I bought a Balance310x and am running the following configuration:
2 x ISP-Uplinks <-> Balance 310x <-> Sophos UTM Firewall
1 x VDSL 100/25 Mbit (idle 10ms)
1 x Cable 500/50 Mbit but only delivering 300/20Mbit/s (idle latency arround 22ms)
The Cable Uplink is configured as drop-in mode with the firewall
VDSL uplink is in NAT mode.
NAT on the Sophos Firewall is active.
A speedfusion VPN with 5 sub tunnels is configured to a speed fusion hub provider for testing purpose. All 5 tunnels are configured with Cut-off Latency 150ms and Suspension Time after Packet Loss 100ms on both sides.
I testet all 5 subtunnels by running speedtests and packet loss tests (onboard speedtest on the Peplink and browser speedtest on client)
Here are my first test with Bonding_vpn tunnel:
The speedtests are showing strongly fluctuating results between 80-150 Mbit/s for download and 18-22 Mbit/s for upload. I would have expect a much better bandwith in bonding mode. (total sum of boths uplinks minus 25% overhead - > 300/35 Mbit/s.)
Download: While running the speedtest the monitored latency for every uplink (via Status/speedfusion) while downloading is not exceeding 40ms and there is no packet loss shown.
I am wondering what causes the peplink to limit the bandwith when no packet loss and no latency exceeding the cut-off limit of 150ms is occuring for every single uplink of the tunnel ? Why is the resulting bandwith of the bonding so low?
Upload: While testing the upload speed the latency of the uplinks vent up to 500-1000ms and there is packet loss some times.
I’m wondering why the cut off mechanism is allowing a throughput that is is causing such high latencies on the uplinks.
