Well then ICS would not be applicable unless your willing to keep the "ICS server" active just like you would for a router.

So as others have already stated you would need to a routed device that supports NAT, your SG250 does support basic routing however it seems it doesn't support Network Address Translation (NAT)

Hello!

I looked at how much the device that I need (level 3) costs, it is more than $ 1000, so as you said, I can use a computer as a router, I will buy another computer and it will distribute the Internet through my switchsg250 to my entire network! Thanks for the advice!

Sincerely,

mxl

Hello,

what device(s) are you looking at ? $1000 sounds very excessive, you can get a decent Internet router for about 100 or 200 dollars.

Which country are you in ?

Hello,

do not buy that device, it will be a waste of money. It is a switch, not a NAT capable router. 

I suggest to go to a local store and let them advise you what you need. Who is your ISP, and what country are you in ?

Hello 

Looks for something like a cisco 1921 which should be applicable and wont cost a lot either, but  please note that they will be cisco EOL

If you do not like to spend money, then look Mikrotik or Pi router :
