I have problem with pppoe connection which I don't know how to solve
no web policy
tried changing port (on port 2 connection was terrible)
Problem is that pages are loading slow, after I press "enter" on url nothing happens for 10 seconds and then it start to looking for page. I checked on multiple pc's, diferent browsers and directly plugged to lan port (without other clients). Internet speed is about 200 mbps faster on ISP equipment. Behind XG I get around 350 download and 200 upload.
Maybe this has to do something with dns but I don't know how to troubleshoot.
A good indicator of troubleshooting is developer mode of your browser.
Press F12 and check the Network tab.
There you should find an information about delays.
Can you check if the status for DNS is resolving properly from GUI with Test lookup ?
Please go Configure -->Network -->DNS-->DNS Configuration, click on Test Name lookup and add sophos.com click the Test connection?
Have you checked the issue with mss as per the below command from CLI?
console> set network mtu-mss Port2 mtu 1492 mss 1412
"Sophos Partner: Infrassist Technologies Pvt Ltd".
If a post solves your question please use the 'Verify Answer' button.
After I execute that command I cannot browse internet any more. Need to return to old settings 1492/1444
does this mean something?
Please check the status for the below commands
system appliance_access show
system firewall-acceleration show
console> system appliance_access show
Appliance access disabled.
console> system firewall-acceleration show
Firewall Acceleration is Enabled in Configuration.
Firewall Acceleration is Loaded.
can you disable firewall acceleration and check website loads ?
Since when you identified the issue, any change done on upstream router and caused the issue?
May be live session is required to generate proper logs and investigate the issue along with packet flow from Sophos firewall
Have you raised support case ?
Please check if there is no issue with mss too as tcpdump you shared not having enough information
console> set network mtu-mss Port2 mtu default mss 1380
Please revert the old settings if no change is found
Aslo, check the interface negotiation 100FD or 100HD ,you may also check if there is any negotiation issue between WAN or LAN with the next-in-line device.
Open Console go to Option 4 and type ethe command
console > system dia uti band "press 'u' twice"
Check if there is any error's E/S (error/second)
If so then lower the link speed.
Also, another step provide us the output of the command;
Console> sh net interfaces
Please check SSL/TLS Inspection logs as well and share the output
