Hi List!

I am new in NetBSD and my english is bad.
I have a NetBSD gateway/router for my LAN my Internet Connection is xDSL
from inode.at/Provider i make the connection with pppoe.
I have a problem when i try to upload/delete a Folder on a Ftp-Server it
doesnt work after sometime when uploading/deleting the Folder cames a
Error:   "Time Out" or gftp dies. I tried with a OpenBSD 3.8 and there
was no error it works.The Error comes just whenn i have Folders with
some Subfolders and Files. When its just a big File exmpale with 60mb
there is no problem.
Sorry for my english.
