Description of problem: https://access.redhat.com/documentation/en-US/Red_Hat_Satellite/5.6/html-single/Proxy_Installation_Guide/index.html#sect-Red_Hat_Satellite-Proxy_Installation_Guide-Requirements-Additional_Requirements That page lists port 5269 Outbout as being required. In reality port 5269 Outbout and Inbound are required. Please either change the direction to "Outboud / Inbound" or add another line for "Inbound". Thanks.
A better link that's not to the html-single variety: https://access.redhat.com/documentation/en-US/Red_Hat_Satellite/5.6/html/Proxy_Installation_Guide/sect-Red_Hat_Satellite-Proxy_Installation_Guide-Requirements-Additional_Requirements.html
