    Our 3rd party proxy is blocking your site.

    Asked by kpowers on January 16, 2012 at 03:01 PM

    What IP addresses should I have our firewall team allow Port 80 access to as they block port 80 outbound from our network.

     

    Thanks

    I will assigned this 2nd level to confirm exactly what IP addresses you need to allow access to.

    We are using a DNS based security proxy called CloudFlare. So, our IP addresses always change. This is what I found:

     

    CloudFlare uses the following IPv4 address ranges:

    204.93.240.0/24 (204.93.240.0 - 204.93.240.255)

    204.93.177.0/24 (204.93.177.0 - 204.93.177.255)

    199.27.128.0/21 (199.27.128.0 - 199.27.135.255)

    173.245.48.0/20 (173.245.48.0 - 173.245.63.255)

    103.22.200.0/22 (103.22.200.0 - 103.22.203.255)

    141.101.64.0/18 (141.101.64.0 - 141.101.127.255)

    108.162.192.0/18 (108.162.192.0 - 108.162.255.255)

     

    CloudFlare uses the following IPv6 address ranges:

    2400:CB00:/32 (2400:CB00:0000:0000 - 2400:CB00:FFFF:FFFF)

    2606:4700::/32 (2606:4700:0000:0000 - 2606::4700:FFFF:FFFF)
