Hey everyone ! Found a crazy bug, took me alot of time to figure it out.
Currently we have USG310 with all features- antispam, idp and etc.
4.31(AAPJ.0)
We had problems with downloading files. The download just dropped randomly. Then I figured out when I disable AntiSpam feature everything works fine for downloads. That drives me crazy
The rule was from LAN1 to WAN all users to any with IDP, AntiSPam, Content Filter, App PAtrol enabled.

So when I enable antispam download of any file randomly drops.

Need assistance. Thanks

    Hi @sk8erbender

    I recommend opening a ticket to Zyxel support, who can help you.

    As far as I know, USG310 antispam maximum session and mail buffer are:

    - Maximum Session: 1000
    - Mail buffer: 50 Kilobytes

    (Source: https://www.youtube.com/watch?v=qegfQK_kpp8  25:50)

    So I suppose, when that values are reached and the Property "Action taken when mail session threshold is reached: Drop session", could be what drops your downloads. But it is pure speculation. 

    I hope you will find a solution to your problem.

    Best regards

    We will run some tests to make sure the fix are merged to the firmware before it is released, so the firmware will be ready around Dec. 19th.
    I will send the firmware to you via private message when the firmware is ready.
