Network with the same IP address as start lease IP already exits choose a different IP address in SSL VPN Settings

Hi sainath biradar : You can not define the LAN and VPN segment with same network. Note has been added in below KBA for reference.

Note: Please make sure that the LAN and VPN assigned networks are not the same.

Please configure the SSL VPN leased network with another N/W to fix the error.

Thank you Vishal for the information
