[SOLVED] Slash Command Issue: Address Forbidden after v4.2 Update

I did recently update to 4.7 and all my slash commands start to fail. I realize that was the issue, but my mmost server is in an internal and isolated network so I should allow any address to use slash commands. I tried *, 10.0/8, 0.0.0.0 but no one works.

How can I allow all IP addresses or disable this feature. Thanks.
