Subject [jira] [Created] (CLOUDSTACK-1633) Why do ACS security groups only support TCP, UDP, ICMP?
Date Tue, 12 Mar 2013 01:25:13 GMT
John Kinsella created CLOUDSTACK-1633:

             Summary: Why do ACS security groups only support TCP, UDP, ICMP?
                 Key: CLOUDSTACK-1633
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.0.0
            Reporter: John Kinsella

If I attempt to make an API call to authorizeSecurityGroupIngress specifying a protocol of
"41," I get an error of "Invalid protocol 41."

Real-world use for this - Windows AD servers attempt to establish an ISATAP[1] connection
between servers. Without opening the firewall, packets will be dropped as shown in the log
