Hi
I am not sure that Skype needs a port forwarding.
However you should that a port is forwarded toward a specific IP
That means that the same port can not be opened toward more than one
computer (one IP).
The way to overcome this limitation is to assign the application in question
different port on each computer.
As an example using Remote Desktop on few computers that are on the same
network, necessitates changing the Remote Desktop listening port.
Check Skype's support for specific information about Skype concerning this
issue.

I have set up a few Skype set ups on different routers / network and
never requires a port forward rule. You are connecting to a Skype
"service" which then "re-directs" to your account / your destination
account.

I understood it needs port forwarding 'for incomming connections' from
following link:

I can't recall doing it, but my router is in fact set to forward both
UDP and TCP traffic to Skype through a particular port. Port forwarding
appears to be a suggestion rather than a requirement for Skype.

This is the only mention of port forwarding I found on the Skype site:

<Quote>
In the quest for even better voice quality, it is also advisable to open
up incoming TCP and/or UDP to the specific port you see in Skype
Options. This port is chosen randomly when you install Skype. In the
case of firewalls, this should be easy to arrange. In some routers,
however, you cannot configure incoming UDP at all (but you still can
configure incoming TCP port forwarding, which you could/should do).

Yes, I suppose that increases bandwidth capacity. I will need it, especially
since I want to use video stream too.
I'll have to figure out if my router supports DHCP reservations. This may be
important for other applications in future on the notebook.
Thanks very much for your replies.
