[swinog] Cablecom Winterthur blocking outgoing SMB connections?

Hi all

With some friends I use a samba server to easily exchange documents. Especialy the windows offline files funcionality makes it the best tool I could find for my purpose.

Now I have two different people reporting they don't manage to connect my samba server. It turned out, both of them live in Winterthur and have Cablecom as ISP.

I have tested the connection from a Cablecom Customer in another town and it worked perfectly.

I would understand if an ISP blocks incomming SMB connections as probably some customers unawarely share their $disk, but outgoing connections?

Can somebody confirm that cablecom blocks outgoing smb connections from customers in Winterthur?
