iPad VPN To Cisco

Hi All

I have a Cisco SA540 with firmaware 2.1.71

I want to create a VPN connection to an iPad2, but after many unsuccesfull attempts I am now stuck

The iPad always says "The VPN Server did not respond"

The SA540 is connected to a 10/100 connection with 15 static IP address's all incoming and outgoing internet traffic works fine, the firewall routes incoming traffic correctly.

I have done much searching on the internet but cant find anything on how to configure this, can anyone advise how the SA540 needs to be setup for this to work?

Please help

Thanks Jon

I'm not an expert on this particular device. I have set up multiple VPNs with a Cisco ASA 5505 VPN router and the connections are fine.

It may have to do with de configuration of the device. Things you'll need:
- AES 128 encryption
- The right Diffie Hellman group (I think it was #2)
- Some other things you can read here:

Thanks for the reply

I have had a look through your suggestions and as far as i can tell, my setup is what you suggest.

One thing I have noticed is in the logs on the SA I get the following when trying to connect the iPad:

Tue Dec 27 17:29:27 2011 (GMT +0000): [Cisco] [IKE] ERROR:  Could not find configuration for xx.xx.xx.xx (500)

Thanks

Is there on both sides of the VPN the same (private) IP range? The 192.168.1.x -range is notorious for this. It also helps if the IP range for the VPN is different from the LAN - provided your router supports this feature.

That now works perfectly

Both sides had the same range, I have changed one side and can now connect to everything via the VPN

Thank you so much for your help
