IP addresses are not being released after SSL VPN connections terminates

Hello,

It seens that when clients terminate an SSL VPN connection, the IP address is not released.

When I check on Monitor > SSL VPN Monitor, it shows multiple IP addresses asigned for one user within the "Active Connections" collum, wich can lead to IP exahustation for new clients.

I've already turned on the "Limit Users to One SSL-VPN Connection at a Time" on the SSL VPN portal settings, but it doesn't seen to solve the issue.

 

Thanks in advance.
