SFOS 17.1.2 MR-2 . Really?

BobbyDigital

ALL,

 

i have upgraded the firmware from SFOS 17.0.8 MR-8 to SFOS 17.1.2 MR-2

 

i'm noticing alot of dropped packets that did not occur in the previous release. I'm probably going to roll back my upgrade.

 

Has something changed in the way the firewall is processing packets and/or rules?

 

I haven't changed anything other than upgrading as recommended.

 

The packets being dropped are occurring on allowed rules.

    hello,

     

    I took packet captures but I am unable to upload them here. is their a size limit on the upload? if so what is the limit. I can truncate the captures down.

     

    Thanks for All Replies

    Hello,

     

    I believe I found the issue. upon reviewing the packet captures I am seeing "TCP OUT OF ORDER" packets which appear to be resulting in TCP Re-transmission. i time stamped the packet captures with the time the issue occurred and the only thing that stood out was this.

    Again, this only occurs when connected to the Sophos firewall. I'm just curious as to why without any changes to my firewall this started happening after the software update.

    If needed I can upload the packet captures.

    Again, thanks for all responses.

    Hi  

    I'm currently investigating this issue with our support team. Would it be possible to please raise a support case including this packet capture you gathered, and sending me a PM with your case ID for follow up?

    Thanks,
