I'm trying to transfer some files through a messaging client like msn messenger. It keeps failing saying to contact the administrator. We have private addressing here so I know that is a problem. I have configured the
cisco router to map a static outside IP to my inside IP, but that didn't help either. We are running NAT on the router. I am assuming some ports need to be opened.. Any help? THANKS!
Yes there are certain TCP ports required, 6891 through 6900, but that may not solve your problem.
The communication initiator in an IM file transfer sends his IP address when setting up the transfer. The problem is that the initiator doesn't know his "natted" address. All he knows is his private address. The other computer can't reply because he can't use the private address.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
