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

Carlo

Hi, 

I have problem with pppoe connection which I don't know how to solve 

MTU 1492

MSS 1452

no web policy

no ips

no DoS

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.

Thanks. 

Carlo

    Thank you. We tried all possible combinations for DNS through GUI but nothing seems to work. 

    I need support from Sophos and ISP for this one.

    In the end, it is easy to find out, who is responsible for this issue.

    Simply do a BPF string in Packet Capture on Diagnostic - Webadmin with: port 53 

    Then filter for your PPPoE Interface.

    If you see packets leaving the interface with the correct IP to the internet (DNS Server), the ISP is responsible for this issue.

    I don't know how to read that

    You read it from bottom to top. 

    So it looks fine from a perspective of getting a response. The question is, what the responsive contains. 

    Next step: Go to the Advanced shell (SSH - Option 5 and Option 3). 

    Then perform the following:

    tcpdump -ni Port2_ppp port 53 

    You should see the requests. 

    14:43:55.259292 PortB, IN: IP 168.63.129.16.53 > 192.168.0.4.6945: 59033 3/0/0 A 52.48.198.35, A 34.255.238.223, A 34.248.210.158 (136)

    That would be a valid response. 

    Please post a snippet from the Advanced Shell.
