I am trying to replace an existing Firewall with IPFire and am having some issues:
Our Current Connection is as follows:
- Static IP from COX business to an Arris Modem
- Firewall uses the Static IP from COX as the outside IP address (Not Certain why this works, but it does, Firewall’s Static Route out is an External IP address not the Modem)
- A Unifi Gateway is used to assign IP addresses.
I have tried to use the same configuration as above but when using the static ip in ipfire there is no internet on the ipfire, there is warnings that the ipfire is not connected to the internet. If I setup Red as DHCP then there is internet on the IPFire and I believe on the Unifi Gateway but no downstream devices have connection. Is there some setting required to allow devices connected to the Unifi system to access the internet on Ipfire’s red interface? I am confused and could use any help you could provide. Thank you
