Question

Windows

Hello, we have a 4g modem that only works on win xp, 7, 8, please tell me how you can make nat so that from the computer where win xp is located and where the modem is connected, the Internet was heard.
external interface 192.168.0.100 internal 192.168.5.5
tried a buggy usergate, didn’t like it,
tried to distribute using standard means, something didn’t work

Answer 1

The easiest way is to share the connection. Then the DHCP server, NAT turns on. Accordingly, all computers on the network must receive the address dynamically.
