iTunes wifi sync through a VPN?

Hi Eric, you're not alone. I'm trying to figure this one out too. I currently have an l2tp VPN configured to my Sonicwall.

I've been giving this a go using ivpn, both l2tp and pptp. Neither have worked. I guess itunes sync runs over bonjour, which I guess the vpn cannot transport.

Rowlandcutler, it's not that Bonjour does not support VPN but rather it's that Bonjour is a multicast protocol which only broadcasts within its own subnet. In the case of my l2tp vpn to the Sonicwall, I am trying to utilize the IP Helper to relay bonjour across the VPN connection. I don't know if the issue is in my rule set where bonjour is not getting across to the remote network subnet or if it is the iPhone which is incapable of listening for Bonjour on two subnets: (1) the WIFI it's connected to before VPN'ing into the Sonicwall and (2) the subnet the iPhone connects to once VPN'd into the Sonicwall. I also have to determine if Sonicwall's l2tp vpn is bridged or routed - as that makes a difference. Bridged is what we want in this situation.

I believe OpenVPN has worked for people but I don't want to jailbreak my phone to get the OpenVPN app. I'd prefer it worked natively to the iPhone.

This is a great discussion. I would love to be able to sync over VPN. I hope that someone will post here if they make a discovery!

If I ever get it working I'll let you know.

I got it to work, in a round about way.

on both the client (the computer your iphone is synced too) and server (the computer you are able to plug your iphone into)

download and install teamviewer from teamviewer.com

install access from anywhere anytime option

install vpn option

google usb network gate by eltima software.

download and install.

add your iphone's usb port to a share in usb gate.

connect to your client with teamviewer and start a vpn.

on the client, connect to a remote usb using the ip address found in the vpn window of teamviewer. the iphone should automatically show up as if you had connected via usb directly to the client computer.

It is a little slow syncing. But it gets the job done if you have to sync away from the home computer

edit:

This is not for wifi. usb only

"on both the client (the computer your iphone is synced too) and server (the computer you are able to plug your iphone into)"

Sorry, I don't quite understand above message. Server should means the computer which installed the iTunes and the client computer should be remote computer which the iPhone/iPad plug into.

Could you please explain which computer install teamviewer and which one install vpn / google usb network gate?

Thank you so much!
