Installation Issue

I am getting the following message when I try to log into the admin.php for the first time.

1. Disable SELinux

My hosting provider support group says, "For the connections to other sites [/#000000]you need to send an e-mail to support@... [/#000000]with the IPs [/#000000]and the port numbers for which you want the firewall to be opened."[/#000000]

I can't find anything in the installation guide to deal with this problem. My question is (and I'm not an IT person) what are ALL the IP's and port numbers that I need to have my provider open?

I'm guessing Port 80? Maybe Port 5? Those are numbers on Line 111 in that file. However I see nothing that looks like an IP and it would seem to me that Google would have a lot of potential IPs (although I'm not sure why we're connecting with Google in the first place).

Can anyone assist please.

UPDATE:

Here is what my hosting provider sent me back.

Please fill out this form:

Please allow the outbound connections for scripts for FTP username: XXXX
Local script filename (and location) which needs the outbound connection:
1.

Please note that our firewall is IP based. If the remote host changes its IP address in the future, please notify us of the change.
