Any VPN have 

Client and server (GW)

Here you have two PC i.e. two clients so there is no vpn for this case

Hello,

Current two PCs can communicate each other becuase on same LAN. So i need to creat VPN and access the VPN using lan connection, right?

If one device connect to device like SW or router can work as  VPN GW then you can use l2tp vpn make PC (in internet) appear as it direct connect to same LAN of internal PC.

You need GW for this VPN

Hello
you do t mention what the pcs operating systems are but most vendors allow to share their internet connection - in windows it’s called ICS internet-connection sharing 
Based on you OP it seems this would be the most simplistic option for you

Hi..

Both PC running under windows 10. ICS as i know this is for sharing connectiion across network card on same machine, how ICS can share the connection to otjer PC in same LAN?

[paul driver]

Both pcs are connected to the same lan correct - if so they share each others internet connection

As we can see in the picture, PC2 have internet access and not for PC1. The firewall control which ip can be connected to the internet or not. Now with this topology how ics can make PC1 able to reach to the internet via PC2?

Hello
Looking at the topology you've have posted ,I would confirm you would not need any VPN or ICS.
PC2 is routing via the CORE and FW, with the assumption the FW is performing NAT, so what is negating you from allowing PC1 the same access, Surely it would just be a matter of appending PC1 details to any exiting FW rule base and nat acls that allowing PC2?

Hi..

unfortunately we not have access to the firewall, so need other way.

Hello
Unfortunately thats where you probably need to allow the access, unless its being allowed on the core -  can you share the configuration of the core switch (attached it to a file)
