For best Skype performance, you need to allow all outgoing ports, and map an incoming port to the computer running Skype that matches the incoming connections port in Skype's settings.

We have about 10 systems running Skype in a LAN of about 30 over a 512K ADSL line. We use both Skype-to-Skype and SkypeOut. Never had any complaints.

Our experience was that the Skype service created over 500 connections through the firewall, going all around the world! That was from just one user. Whilst the Skype service was on, internet browsing became very slow for all the LAN users.

Could I ask if your ADSL connection has a fixed public IP? Ours does and I wondered if Skype took more advantage of such networks?

Otherwise, does anyone else have experience of running/testing Skype....

Is it safe?
Assuming our network was becoming a 'super node', how to avoid that to protect bandwidth?

The 500 connection problem only happens for me if the Internet connection is down, then skype keeps on opening ports and retrying. In actual use, it never opens more than 20-30 ports.

When skype is idle the opened connections don't take up any bandwidth, during talking, it takes up 5K in/out.

The IP doesn't seem to have any difference. I'm on a static IP now but it used to be dynamic IP. There was no difference.

I found this article... long but interesting reading

It seems that your experience would indicate your system is luckily a normal user, but our system unfortunately became a supernode.

As a supernode, many blogs and web articles have reports of reduced speed wan and even lan, until the skype app is disabled.
That was our experience also... browsing the web either stopped or became too slow to use, and even connecting to shared folders on the lan suffered obvious problems.

My research suggests there is no control on whether your system becomes a supernode or not. (Skype will just do it automatically if -among other reasons- it feels you have enough bandwidth, a powerful enough machine and are in a geographical location where it needs a new supernode). Mad

So, I guess for Skype it's a try-it-and-see! If your system does not get promoted to supernode, you can enjoy an otherwise handy service. Very Happy Alternatively try www.gizmoproject.com for a voip app that can be controlled!

Skype can't become a supernode if you block the incoming port on Winroute. Since Skype's incoming port number is randomly generated, and you have to map the corresponding port in Winroute, there's no way to become a supernode unless you specifically do so.

The analysis that everyone refers to is long outdated.
