iOS VPN

[bardel]

Hi,

Im trying to setup a Fortigate 60D I have at home for VPN access from my iPhone.

Initially I went through the iOS Native VPN wizard, which didn't work, mainly I think because of the DH Group 14 issue.

So, I went through the cookbook guide and started fresh, again with the iOS Native and then once all that was completed, converted to Custom Tunnel and changed the DH group to 14 on Phase 1.

At this point I was getting negotiation errors, and I followed the information on https://cookbook.fortinet.com/ipsec-vpn-troubleshooting/ as I was seeing "SA Proposals Do Not Match" in the log.

Eventually I had to change the algorithms to AES256-SHA256 before getting past the proposal stage.  Now, I'm still receiving the same"Negotiation with the VPN server failed." message on the iOS device, but using the debug diag in the CLI I can see that negotiation is successful as is the XAuth.

However, beyond this, from my very limited knowledge of router CLI and debug info, it looks like the router thinks the iPhone is not responding to messages and disconnects it, at which point the phone indicates the above error.

The console debug diag looks like this.... (I've replaced the client IP with 123.123.123.123 and the router IP with 789.789.789.789).

Can anyone help me with the missing piece to get the VPN working?

Thanks

Barry

Anyone please?

[patrickjburt]

I also went through the cookbook guide but failed to find out whats wrong with your setting an ios vpn on Fortigate 60D.

Did you get anything on it yet or still receiving the same"Negotiation with the VPN server failed." message on the iOS device???

[rradkad]

Hello,

I am receiving essentially the same errors when trying to setup an IPSec VPN.  Did you have any luck resolving this?

[Hosemacht]

hey there

why do you want to use ipsec-vpn on an iPhone? we have many Iphones/Pads that are connecting via ssl vpn.

works like a charm

Regards

[rradkad]

We were having an issue where connecting in over the SSL VPN client was not allowing the iPad device to use Microsoft's Remote Desktop Client app.  We have since got the IPSec working with the device and able to utilize Remote Desktop Client with it.  There was an old posting that the FortiClient SSL VPN on apples iOS would not allow for the RDC to work with it, and our experience confirmed/validated that.

[mikael_avandal]

Hello!

Maby my config can help you out

Here is a sample config that works.
