block TIK TOK on router 😢

[tiofalm]

Please help blocking the Tik Tok application

[Christian1225]

Use DNS filtering (like OpenDNS or NextDNS) or Block TikTok's domains and IPs via your router or firewall settings.

You can achieve this with QoS and NBAR if you install the most recent protocol pack: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_nbar/prot_lib/config_library/pp7500/release-notes-cisco-protocol-pack-75-0-0.html

After the protocol pack is installed the configuration of this would look something like this:

class-map match-any blocked-apps
 match protocol tiktok
policy-map drop-blocked-apps
 class blocked-apps
 drop
interface {wan interface}
 service-policy output drop-blocked-apps
