VPN issue on IPhone and IPad

[osama_mansoor]

We are facing a very weirded issue when connecting native VPN (IPsec) from IOS-based devices such as iPhone or IPAD that VPN is connected successfully but try to open the intranet-based link the site is not responding when using address with a name, however, when open with IP its open successfully and it looks like a DNS issue as VPN user is unable to resolve DNS, therefore, a website with DNS name is not openinng.

For Example: When i type http://helpdesk.abc.com it gets not connected however when I try to open 10.1.1.100 it opens.

The above scenario is working fine on Windows and Android-based devices (IPSEC).

have you tried to use FortiClient instead of using IOS native VPN feature?

[osama_mansoor]

Yes, I installed forticlient but unable to see where should i put Pre-Shared Key.

tried in my ios device configuration for VPN settings is quite straight IMO.

Name: vpn

Host: FGPublicIPAddress

Port:10443

User: osama

click Save upper right portion of the screen.

Now you will see the ff.

Connections

VPN-->toggle this button, it will prompt you to key in your password. ;)
