Re: TCPIP port restriction for network security

[mcrump@xxxxxxxxxxxxxxxx]

That's correct.  We can only access the outside world on approved ports......

Essentially, I have a user who wants to communicate with this 3rd party
consulting firm via the chat function in Sametime.  It seems to use a different
port than 80 therefore he cannot do it from our location.  But of course, the
more I think about it the more I have to make sure I understand what is going
on.  I may have shot this email out prematurely but I think the general question
is still valid.

Do you really mean closed TO the outside world?  Meaning you can't acess
the outside world except on approved ports?

I allow outbound connections from anywhere to anwhere and only block
incoming connections.
