Ask: How can connect 02 separate Lan's same subnet mask.

[Ngo Tung Lam]

Hi All,

I have 02 Separate Lans Network with IP address range: 172.16.4.xxx/22.
Some PC on 02 Lan same IP address. I will call Network A and B.
Now I want to only 01 PC from network A (eg IP: 172.16.4.161) pull data from 01 PC on network B.(eg IP: 172.16.4.185) but on Network A had PC already got IP 172.16.4.185. Our network dont allow for change IP address by control reason.
I was I am wondering if someone on the forum can give a solution?
How i can do that? Any devices (firewall,etc)need install between 02 network?
