QUIC Protocol Blocking RDC.

Hi Sophos Community,

Currently here at our office we blocked all Gmail Accounts except our domain which is "@example@gmail.com" i enabled the Decrypt & Scan HTTPS and under application filter disabled the protocol "QUIC" in this set up i can successfully block other domain login on Gmail. but now i discovered that applying this set up blocks remote connection desktop on clients under this firewall settings. is there any workaround or exclusion policy to apply to our firewall?

Thank You.

Hi Gabriel,

Can you show us a picture of configuration? I would suggest you to drop the UDP 443 service through a FW-rule positioning it on the TOP.

Thanks

Hello Gabriel,

Would you try to create a exeption for RDC?

Hi Sachin,

I searched the UDP 443 in application filter but it did not return any result.
