I have mission to implement firewall to link the two company from different floor which is 1st floor and 5th floor.Both company have their own network and internet gateway .1st floor gateway is 192.168.100.1 and 5th floor gateway is 192.168.1.1.Our mission actually is use the firewall to link this company network together without major change in client site and both network should be interlink .I already draft the diagram before and after.I believe from my design from the 192.168.1.0/network should be able to connect to 220.127.116.11/24 network because all the client gateway is 192.168.1.1 but from the 1st floor due to all the client is 192.168.100.1 so this may not connect to the 192.168.1.0/24 ,please advise how to overcome this issue.
