Cisco ASA AnyConnect setup?

Question

Cisco

In general, the essence of the issue is this, we have the institution's LAN 10.144.116.0/23, dhcp works in it, the range from 10.144.116.100 and further to the end is used. There was a need to organize remote access from home computers to work computers, but at the same time, 150+ free addresses within the network are needed, but there are none.
There is an ASA 5512-x firewall, when setting up the issuance of addresses within the same network, everything works, but if you set some other range, for example 10.50.50.2-254, there is no connection. I can't figure out what I'm doing wrong or what I might have forgotten to turn on?
