Problema com Whatsapp web Sophos UTM 9

Good afternoon,

I have a Sophos UTM 9 System with several Social Network filters and group of sectors.

User is connected to a wired network, and uses the social network Whatsapp WEB ... I have a problem sending media via the WEB, by cell phone he normally sends the media, but via Whatsapp WEB he keeps loading but does not send ... I adopted a free access policy where there is no restriction and it worked normally but I cannot leave this policy to users because if I have no problems on the Network. I've already analyzed the filter in every possible way and I can't find where the Whatsapp Web block is ... I look forward to returning,

Thanks.

Just to be sure: the group definition is ok? The Firewall rule is activated ?

Do you see any drops in "Live Log"?

Ahemm, another question: the "normal" Ports are opened to the Internet?

I mean, is HTTP Port 80 and HTTPS Port 443 allowed, too?

The setting on the firewall as I see it is ok ...

No rejection appears in the live log, no blocked logo appears ... it only blocks at the station and nothing appears in the log

Hello,

the problem occurs at a user's smartphone, right?

Is the Wifi this smartphone is connected to on the same LAN segment, where your interface "INTERNAL" is connected to?

If not, then none of our rules would apply to that device.

The Smartphone works normally, sending files and video calls ... the problem is on the whatsapp WEB site, where customers need to use to send documents.

Still not working

Hello,

as far as I can see, there is only a need for port 5222 and 443 open for this kind of filetransfer form a pc to that portal.

Do you have webfiltering in place?

Olá Vinicius and welcome to the UTM Community!

What do you learn from doing #1 in Rulz (last updated 2019-04-17)? What about when examining the Web Filtering log (read #2 in Rulz)?

I couldn't understand the reasoning. Rulz # 1 I can't disable this option because it is about network security.

Hello Vinicius,

that recommendation from BAlfson was meant for testing only.

PLEASE: Why don't you just test it and report your findings?

Same thing about my other questions: you did answer a third of them, the others you don't care about...

It's hard to help you like that, because we need to pose questions to clarify what you are doing.
