Owncloud at home and bandwidth

[Mérof 42 <merof42@gmail.com>]

Hi,

I installed Owncloud on a new install of wheezy on a "server" at home.

I use apache2, php5 and mysql, and I redirect the port 443 on my server.

It is work fine, but I need to limit the upload bandwidth to Internet.
I have a 1mb/s upload adsl, if I share a file with other people, it could saturate my connection.

This server is also ipv6 compatible, and I use only ipv6 at home between my computer.

Actually I use wondershaper to limit upload on eth0 at 512kb/s, but it is limited also for my lan, it is silly.

I'd like to limit upload only for external request, but not for my lan.

Do you have any idea how can I do that?

For people who don't know, Owncloud is a dropbox like who can be installed on your own server.

Thanks you all.
