no work Google Service, Protocol Quic,, Help me plz (Лучше по русски конечно )

Hi @grinnZli !

You didn't mention hosts in which security-zone have issues with QUIC protocol, but I assume they are located in 'Local'.

I am not an expert in QUIC protocol, but since it uses UDP I think you need to perform following modifications:

acl advanced name Untrast-Local
 rule 10 permit udp source-port eq 443

The thing is that unlike TCP sessions which state router can track by 'established' keyword (it tracks the Acknowledgment (ACK) or Reset (RST) bit), UDP segment's header doesn't have any information about sessions - every UDP packet is independent from others and if application needs to track sessions, this tracking must be implemented in Layer 7. Therefore you need to explicitly allow return traffic from servers that use QUIC, otherwise your ACL will just drop it.

did not help! Waiting for a response from your internet provider

Hi @grinnZli !

I advise you to try a permissive ACL "acl advanced name Untrast-Local" - just put "permit ip" on the top and check if QUIC will start working. If it will, then check QUIC documentation (if any exists) what traffic should be allowed on a firewall or router in order to bypass this protocol inside your network. However, if even with permissive ACL the QUIC won't work, then the issue is definitely outside your router.

no work! 

QUIC doesn't work with permissive ACL? 

yes! QUIC doesn't work with permissive ACL

I see. So it is either your ISP or maybe another ACL that we overlooked. You need to check the return traffic flow from Google to your hosts - which interfaces it traverses and which ACLs it may hit before reaching your internal PCs.
