XG cuts bandwidth to the half

mxull

Hi all,

i have the issue, that when I use my xg the internet bandwidth cuts to the half.

I have a 200 Mbit connection and when i am using the XG i only get ~ 90 Download / 10 upload
When i am directly connected to the provider router i get 190 Mbit, so i think the connection is ok.

 

Settings:

- XG 115w
- interface is connected via 1000 Mbps - Full Duplex
- firewall rule on top with no ips, qos, web or application
- System Services -> Traffic Shapping Settings is set to 200 000

Did i forget any options?

 

I am thankful for every tip!


Regards,
Max

    Hi,

    We are facing the same issue, WAN speed can only achieve about half of the subscribed speed. Which is about 400mbps over a 800mbps line and Sophos engineer failed to rectify the issue.

    Any update in this thread?

    We are using XG125. Sophos support case ID: 8977402

    Thanks.

    Hi KL,

    Parameters XG125 (below) indicate that 800 Mbps is unattainable. In my experience for XG125 rev.2 with protection functions enabled it is max 450 Mbps. XG125 rev.3 should be a bit faster. The heavy load causes IPS. It should be noted that IPS works even when it is not used in rules. You can disable the IPS service but is this a good solution?

    rev.2

    rev.3

    Hi, Jan,

    Noted your prompt response which also explained why Sophos support unable to assist as we have hit the hardware limit of the XG125 Rev.2

    We are now getting precisely 450mbps and that is a little low considering we paid for an 800mbps line.

    What would be your suggestion? Replace with XG125 Rev.3? Or XG135? Or we can never get 800mbps due to the IPS overhead unless we get 1.6Gbps line, just to get 800mbps..

    Your suggestion is much appreciated.

    Thank you.

    Hi KL,

    Currently only XG125 / 135 rev.3 are sold. To make full use of the 800 Mbps band, XG135 rev.3 would be needed (XG125 has weaker parameters, especially AV proxy). For the 1.6 Gbps band, an even more powerful XG210 would be needed. You need to consider the profitability of the investment.

    Hi,

    do you expect one suers to pull the 800mb/s or multiple users.

    Try running two concurrent tests on different devices and see if you can achieve your desired throughput/
