Issues After 9.405-5 update

x12Mike

Hey All,

  I noticed under the VPN section that there have been issues with the SSL VPN connections, however ever since I updated to 9.405-5 last night, almost all secure traffic I try to send (HTTPS & SSH) traffic seems to fail and not go outbound.  Or a better description, is that I can make an HTTPS connection to a site, and if I try to continue to browse the site, the connection times out or resets....  SSH connections to systems have been failing too.. i can ping these systems, but secure connections fail...  

  Am I going nuts here with this, or are my issues, and the SSL VPN issues potentially all related?

    Hi Mike,

    What do you see in the packetfilter.log? What is the operating mode deployed for Web protection in the UTM? 

    Also, try changing the DNS forwarders in the UTM.

    Thanks

    So what is very odd, is that this appears to (so far) only be affecting my linux clients...  And on top of that, it might only be interesting traffic to remote systems over my VPN's that's affected...  (Apologies, I am testing while I write this various scenario's to see what works and what does not)

    In the firewall log, there is nothing being blocked, things are traversing fine.  For Web Protection, the VLAN that I am dealing with is not in there...  I do web protection for my Guest LAN, not my main Private LAN where I am having issues.

    Current DNS forwarders are Google DNS (8.8.8.8 & 8.8.4.4)

    So far, this may just be a VPN issue, and on top of that, one that is only affecting Linux clients...  which makes no sense to me at all, but who knows... :)

    I'm going to need to delve into this more when I get home this evening...
