Can we allow all outgoing connections on CSF cPanel?

[Brantdus]

Hi,

I'm using cPanel to host several websites. There is a client that owns a "check for the open port tool" website & he needs all ports to be open. So here is my question Can I open all TCP OUT ports? Will it be safe?

I'm not a security expert If it's not safe, could you guys explain to me why?

Thank you.

I do not recommend to open all the outgoing ports. It would be a huge security issue to do so, and If your client requires all open ports, then he should be on a VPS, not a shared server.

no, you cannot open all outgoing ports. it would cause security issue
