Ok here's the solution, you can search on Document ID:2000122012575248 and
hit this one doc from the public Symantec KB.

Which ports are used for communication in Symantec Quarantine Server 2.0? 
Situation:
You want to know which TCP ports are used by the Symantec Quarantine Server
version 2.0 to communicate with the Symantec Security Response (formerly
known as SARC) auto-response server to submit quarantined files. You want to
know whether opening these ports at the firewall will expose your network to
security risks.
Solution:
By default, Symantec Quarantine Server 2.0 communicates with the Symantec
Security Response auto-response server using the static ports 2847 and 2848
and only require Outbound traffic be enabled. These ports are used by the
Quarantine Server to submit viruses using the Scan and Deliver option. These
ports are closed after the submission is completed. Symantec Quarantine
Server also connects to the Internet using port 80 to obtain virus
definition updates. Opening these ports at the firewall to allow outbound
traffic from the Symantec Quarantine Server should not pose a security
threat.

Hi all,
I don't want to jump the gun and make this something its not, but this
posting bears very similar resemblance to an issue I was working on with a
client.
At approximately 13 minute intervals my client was seeing repeat traffic
through his network to very similar addresses from a handful of clients.
This was so bad it was choking his internet connection.
After some analysis of log files we had some machines to work on, we
discovered on each machine there was an illegally downloaded copy of Norton
anti virus, that continually (13 min approx intervals) was downloading
update files and not applying them, therefore, it would continually repeat
the process throughout the day.
Could this be a ddos?

I don't know if this is the proper forum for this question so if it's not
I'm sorry.
Appended is an excerpt of a log off of one of our firewalls. I think that
this guy is using AIM but I can't determine. The only thing I could come up
with for port 2847 is the AIMPP-Port Req (from all the port lists) and
nothing for 2848. 192.168.100.2 tries to connect to 206.204.212.226 on port
2847 then 2 minutes later to 206.204.52.98 on port 2848 then again to
206.204.212.226 13 minutes later and the pattern repeats. Do you think this
has anything to do with AIM or could it be some other software application
that uses these ports and the port listing for 2847 is not entirely correct?
