Sharing iTunes over VPN

I might be wrong but I beleive iTunes sharing uses Bonjour networking, rather than IP. Bonjour will only work on local address ranges and therefore can't be routed via VPN.
hth,

iTunes uses the broadcast and multicast addresses of a network which are not present over VPN. So you're out of luck doing this. There are ways to reroute these packages and increase their TTL but they are way beyond the work you want to invest into that.

Yeah this works, here is how i remember i did it when i followed a guide i can`t dig up. But it`s pretty simple:

#1 Set up VPN connection between the two locations (done)
#2 Download and install RendezvousProxy (Link below). Afaik it tricks your computer into thinking it is in the same subnet as the address you feed it.

#3 (Alternate solution) Download and install Zerospan (freeware) set up to do the above for you: http://www.zerospan.org/

I have no idea if doing what you want to do, or the method described above is in violation of any apple rules or distribution laws. I`d assume not, but you can never be too sure:)

edit: Also remember port configuration on your computer and router (if you use one) so it allows traffic on whatever port you chose. If you have a router you probably need to set up forwarding to the computer thats hosting the itunes library.

edit2: And if you don`t have a static ip where your itunes library is hosted, you could set up a deamon with www.dyndns.com so you don`t have to change the address manually every time your IP changes.

Btw, hope all of this helps. Keep us posted!
