SSL VPN using two internet links

Hello guys,

So, I have an SSL VPN using two different internet links, my users are able to connect using both links.

In this case, how can I see how many users are using link one and link 2?

I tried some commands but, they show the status and Source IP Address but none of them shows me what link the SSL VPN users are using. 

the closest command was: get vpn ssl monitor, even in the dashboard I can see how many users are connected, but nothing about what link they are connected to.

Thank you, guys.
