Home XG - 18 MR4 - Some Sites Not Loading

Hello,

Running XG 18 MR4 at Home on VMWare.  Last night I noticed that all of a sudden some sites - Yahoo.com, Netflix, CNN, Showtime, and others quite loading.

Google Worked.  SSL VPN to my office partially does.  Auth Pages load but nothing else.

Havent made firewall changes in 3 months.  Only Errors I see to IPs I am having issues getting to are "Could Not Associate Packet to Any Connection".

I did notice SOPHOS activated a new AV Definition during the same time the issues started.  I have rebooted.  Rebuilt from Config Backup and nothing.  Same Issues.

See no other errors in Logs.  I have disable all the IPS, AV, Web etc on my LAN to WAN Rule.  Going to try a fresh new install with new config tonight.

My question is - Is there a clearing command to reset all the connections or something in the FW?  When I bypass the Sophos all works to the Internet.

  • Hi Rob,

    doesn't sound like a local issue, but an XG service issue. Pleas review your firmware update time schedule to see if a newer versions have been installed?

    Also what are the current versions that you are seeing this issue with.

    The error message implies that your network has dropped and needs to be checked, but you have advised you restarted the XG,did you restart the VM?

    A quick way of resetting the external interface is edit it and then save without making any changes.

  • Av updated around the time it stopped working.  Rebooted vm and host.  Also did a fresh install same issues with bare config.  Did pppoe on my laptop to bypass and everything is working.  Same sites with issues.  ISP has no other reported issues and the bypass proves that.  Tried lowering mtu.  Rock solid for a couple months and now this

  • A restart will clear all connections.

  • I had to temp install pfsense until this is figured out.  Community.sophos.com will not load as an example.  Super wierd.  Like I said I did a fresh install of v18 mr4 with just base rules and I see the same issues with same sites.

  • Did you reload your old configuration into the new build.

    please try a simple lan, lan, wan, any allow all rule with the default mass Nat.

  • Reloaded a backed up config from the previous week on a fresh install XG.  Same Issue.  

    Installed a fresh copy XG with Simple WAN/LAN config.  Same Issue.

    Connect my laptop to connection and Iniate PPPoE.  Everything works.

    Installed a PFSENSE WAN/LAN config and everything works.  

    Sites that Do not Work constantly show 

    "Could Not Associate Packet to Any Connection" in logs

    CPU I noticed is running high as well.  Makes Zero Sense.

  • Hi,

    the error is either there is no firewall rule matching the request or the connection has ended and you are seeing dead connections closing and can usually ignored.

    What do you see in logviewer -> web when this occurs?

  • I checked all the logs and they were clear.  What's odd is that it always showed a LAN IP which doesnt make sense.  I fired up my Sophos VM again tonight and forced  a pattern update and it seems better.  What is odd is that I noticed the issues after the AV update Tuesday Night.  it is now on 1.0.16600 and happier.  Guess we will see.

  • i am a new Sophos XG v18 home user and i experienced the same issue but with the Android Wells Fargo app while my phone was on wifi.  The Wells Fargo app would display  "System Temporarily Unavailable" right after login in.  i thought Wells Fargo was doing temporary maintenance but then i turned off my phone's wifi and re-tried again using my phone's mobile network connection and the app worked.  So in my Sophos LAN-to-WAN firewall rule, i changed the "Web Policy" from "Default Policy" to "None" and re-tested the Wells Fargo app while my phone was connected to wifi and the app worked.  i went to Web/Policies/Default Policy and removed "Advertisement" out of the "Suspicious" activities. Then i went back to the LAN-to-WAN firewall rule, "Web Policy" and selected "Default Policy" and the Wells Fargo app worked.
