Stop VPN Disconnecting when going to Sleep

Question

When the iPhone (4) goes to sleep, the VPN will disconnect. Is there any way to disable this behavior as it's sometimes a bit annoying.

I am jailbroken, and the server I'm connecting to is Windows Server 2008 R2 which I can edit settings on.

Answer 1

The VPN will disconnect because your WiFi disconnects.

Therefore you would have to...

• either reconnect your VPN connection when on 3G (How?)
• or enable your iPhone to keep connected to WiFi (requires jailbreak)

To keep WiFi on in sleep mode you need to install KeepAwake via Cydia.

See this step-by-step guide.

Answer 2

I would expect that sleeping an iPhone and staying connected to the network are incompatible goals. If you don't want to drop the VPN connection, you need to keep the device awake.

However, I found a discussion on apple.com that states that plugged-in devices are able to maintain network connections while in sleep mode.

Answer 3

I did 2 things and now the VPN does not disconnect even while switching from wifi to 3G.

1. Install Cisco Anyconnect to connect to VPN network.
2. Install KeepAwake(from cydia) --Thanks, gentmatt

Now it's all fine, i can work from anywhere on my 3GS and VPN remains connected while on the move also.

Answer 6

a workaround that I found was on a jailbroken device, use activator and link unlocking device to a toggle to turn on VPN. Therefor every time I unlock my device the VPN reconnects so I am happy :)
