Accessing Public IP of a Client behind a VPN

Hi, im fairly new to mikrotik. I have a server (server 1) with a static public IP 45.32.x.x address that connects to a mikrotik VPN server (IP address 139.180.x.x) thru L2TP/IPSec. The server assumes the VPN IP address 139.180.x.x however, is it possible to access server 1 using its original static public IP address from outside the network? (see attached file). Thanks!

If the IP 139.180.x.x is actually announced upstream of the l2tp+ipsec server, it is certainly possible. they are probably rotating it with IP PTP of the L2TP itself
