I use a product called Untangle and it has a bandwidth monitor.  However, I'm not clear on what it is displaying.  See attachment.  The first IP is Comcast.  The second I couldn't find.  Should I block them both?  Should I be concerned?
Any advice would be appreciate.

Hi

I had the same issues with some users in my organisation, but I'm using Fortinet to check which user ip address is consuming more bandwidth than usual and I always block the destination ip address.

he was indicating if the traffic was outbound....
looks like u meant inbound

you can check the ip and ports

ip = comcast
ports some are realistic...exchange active synch

when in doubt tho block the foreign address and see what happens
could be malware on you network that reaches out and is getting return traffic

i access comcast a lot ...even work or anywhere
it is my email provider...
and sometimes i get caught in looking at the news if I have time

usually they are decent and they do spend a lot of resources making sure the traffic is relatively clean

monitor the situation and see what else transpires.....
it is always a good idea to have a baseline anyway and know whats running on your network

the more time you spend with some networking tools
or looking at the firewall or router - you'll have a better handle on whats 'normal'

and then it a tad easier to spot odd traffic

the newer firewalls - NGFW - Next generation Firewalls are specifically designed to identify the applications running on our network by looking at all the traffic and then letting us know what it is - s we can control it

like  a Palo Alto - beware they are not super cheap...lol ... but very good

If you research the port number, 9600, it comes back as "MICROMUSE-NCPW."  A quick search of MicroMuse comes up with: http://en.wikipedia.org/wiki/MicroMUSE 

It is an online Role-playing game of some kind.  So one of your users seems to have a lot of time on their hands at work, enough time to play role playing games ;-).

Though it's extremely old... It still seems to be around via: http://www.mudconnect.com/mud-bin/adv_search.cgi?Mode=MUD&mud=MicroMUSE 

Hope this helps.
