How to whitelist ip to a specific domain

What you are asking is not really possible with iptables. You can, however, restrict access to certain IP addresses using your web server configuration.

For Apache 2.4, you would use a Require directive; if you're using Apache 2.2, there is an older syntax using Allow, Deny, and Order. I presume that nginx can do this, but don't know how to configure it.

OK. Thank you for responding. This helps me change direction in my research on this. I'm running nginx. So now I just need to figure out how to do it from there.

Thanks.
