I am trying to configure a Firewall in my network using 2 different Lan interfaces, but when We go to internet, I need to specify to go with a public fixed IP.
All the computers in my lan use the range 192.168.0.1/24 and the LAN interface of the Zeroshell server has got the ip address 192.168.0.1 and is the GATEWAY for all other computers.
The WAN Interface of the Zeroshell server has got the ip address 192.168.1.1 and it´s gateway is the ip address of the router which is 192.168.1.99
This router is configured to send all packets directly to 192.168.1.1 so I need to configure the server to do SNAT with the external ip address given by the provider.
Can anyone help me with this change? please.
