Ensure the following to make Zoho Meeting work beyond the system firewall,

1. Exclude domains in the firewall and proxy settings

2. Allow certain ports in firewall settings

3. Include executable files or exclude directories in the firewall.

Domains

Exclude TCP and web socket protocols for the following domains from your firewall and proxy settings

• *.zoho.com

• *.zoho.eu

• *.zoho.in

• *.zoho.com.au

• *.zoho.com.cn

• *.zohomeeting.com

• *.zohomeeting.com.cn

• *.zohomeeting.jp

Now, Zoho Meeting has mapped all the IP addresses of our global Gateway network, to a single domain name, mediaserver.zohomeeting.com. Zoho Meeting will communicate to the destination port received when the client makes it connection. The firewall should be configured to allow these connections.
