Question

IPsec VPN connection

I need to know about IPSec VPN for a FortiClient VPN tunnel. Are there any limitations to using a single WAN interface? I have already created an IPSec VPN tunnel for FortiClient, and it works perfectly. However, I created another tunnel for the same WAN interface, but the new one is not connecting with FortiClient VPN.

 

Please help me resolve this issue.

 

version - fortigate 1500D 7.2.9

Hi @noc_92 ,

 

You did not share your IPSec VPN configuration, so I am not sure how you configured it.

 

For your use case, you need to:

 

1) Using Aggressive mode in Phase 1 settings;

2) Using Peer ID for IPSec VPN tunnel selection;

 

So please check this KB article about how to configure it:
