IPsec VPN with HotSpot connection

[AnonymusUser]

 Hi, we have two remote users accessing via mobile hotspot, and they encounter this problem: when the FortiClient establishes a connection, they lose their internet access. If they press diconnect the VPN, the internet returns.

Be aware that when they are linked to the VPN, their internet symbol changes to this ( screenshot1)  and when they disconnect it goes back to their hotspot symbol.( screenshot2)

Hi Anonymous

You probably need to setup split tunnel or split DNS. To do so you need to have admin access on the remote FortiGate.

You can check the current status as follows:

• Once connected to VPN, run nslookup and send a DNS query to see where is it sent
• Once connected to VPN, run netstat -nr to see if default route is injected by VPN

Hello, we determined that the primary issue was their hotspot connection, as this problem ceased once they logged into Wi-Fi.
