Office relocation, changing the new WAN IP address with new LAN IP addresses assigned by landlord.
Hello, I urgently need help. My office is moving to a new location.
The internet connection is managed via the office landlord.
I received information about the internet connection..
I have been given a static public address and a LAN IP address with GW.
However, I need to keep the old LAN settings because I have multiple servers in this network.
Firewall is FortiGate 81F
new connection
Public IP: 87.xxx.xxx.xxx
LAN IP: 10.48.200.2/24
Gateway: 10.48.200.254
old connection on firewall
Public IP: 104.xxx.xxx.58
Gateway: 104.xxx.xxx.57
LAN IP: 192.168.2.1/24
no DHCP, all clients receive through Windwos DHCP, 192.168.2.1 is GW for clients
Is it possible to use the new internet connection with the existing LAN 192.168.2.0/24?
Do I have to apply the new public IP Address for WAN and LAN settings for internal,
-> setup route interface WAN to 10.48.200.254
-> and then set up another physical interface with LAN 192.168.2.0/24
-> set up interface 192.168.2.0/24 route to 10.48.200.254
Unfortunately I can't test it in advance but directly during the move
Is this the right way? Or how can it be solved and what steps are necessary.
I am grateful for any help.
