How can I ensure Feishu functions properly on my company's intranet?

To ensure Feishu can function properly on the company's intranet, the company will need to configure the following domains and IP configuration allowlists on the firewall:

1.Domains that need to be on the Feishu app's allowlist

•"*.feishu.cn"

•"*.feishucdn.com"

•"*.zjurl.cn"

•"*.snssdk.com"

•"*.pstatp.com"

•"*.byteimg.com"

•"*.bytedance.net"

•"*.bytedance.com"

•"*.byted-static.com"

•"*.bytegoofy.com"

•"*.weboffice.feishu-3rd-party-services.com"

2.Video meeting domains and IPs that need to be on the allowlist

•Signaling service:

Domain	Protocol	Port number	Direction	Access type
.bytedance.com .bytevcloud.com	TLS	443	Out	Signaling service

Note: If you want to use effects in your Feishu meetings, you will have to configure additional domains for the effects' resources. To ensure video effects can function properly on the company's intranet, the company will need to configure the following domains and IP configuration allowlists on the firewall:

•Domains that need to be on the app's allowlist (effects)

◦Port domain:

▪effect.snssdk.com

◦CDN domain:

▪lf3-effectcdn-tos.byteeffecttos.com

▪lf6-effectcdn-tos.byteeffecttos.com

▪lf9-effectcdn-tos.byteeffecttos.com
