I have a server behind a proxy. I need to whitelist the proxy ip. I'm new at this.
I have tried the code below
/sbin/iptables -I INPUT -i eth0 -s 188.8.131.52 -j ACCEPT
The Ip isn't real just example.
I think it worked i'm not sure if thats permanent solution.
If I restart the server will it stay whitelisted?
