PPPoE connection on XGS 2100 SFOS 19.0.0 GA-Build31 - slow page loading

Hi Carlo

How about you connect PPPoE directly on laptop and what speet test shows ? and output for ipconfig /all for windows system ?

Please take SSH access of the device and Login to console and execute the command system diagnostics show syslog

Save the PPPoE interface configuration and check the output command for PPPoE and share the output.

You may also execute the command show pppoe connection status

Please refer the below link and update the ppoe configuration : 

https://support.sophos.com/support/s/article/KB-000035683?language=en_US

The web GUI only shows the PPPOE WAN connection MTU value of 1500, and this is the physical interface. The command-line interface (CLI) shows the physical interface and the logical interface. The physical interface for the WAN connection in the CLI has an MTU value of 1500. The logical interface displays an MTU of 1492 and is always deducted by eight due to the PPPOE overhead. 

The only way to drop the MTU for a PPPOE connection is through the web GUI. For example, if the physical interface is 1500 and an MTU of 1484 is required by the PPPOE connection, drop the physical interface to 1492.

To change the mss or mtu use below command

console> set network mtu-mss PortB mtu <value> mss <value>

Thanks and Regards

Thank you for answering.

  Hi Carlo 

Please share current status  for interface speed after expanding Port 2 under Advance setting and logs for below command

tail -f /log/dgd.log

tail -f /log/networkd.log

tail -f /log/dnsgrabber.log

console>tcpdump ‘host sophos.com

Might below command helps?

console> set network mtu-mss Port2 mtu 1492 mss 1412

Thanks 

I was testing in that time different configurations

Hi Carlo 

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

Thanks 

After I execute that command I cannot browse internet any more. Need to return to old settings 1492/1444
