I have a monowall virtual firewall. It is working perfectly with the LAN subnet.
I am using this monowall only for NAT.
I have added a secondary IP on the LAN interface.
From a host on the secondary LAN Subnet, I can ping the secondary LAN IP
I can ping the secondary LAN Subnet host from the WAN interface
I can ping the secondary LAN host from the LAN interface
Firewall rules are any any for both the LAN, secondary LAN and WAN
I cannot ping the WAN interface IP from the host. I cannot ping any outside destinatations.
LAN - 192.168.71.1 /24
Secondary LAN 192.168.72.1/24
I need the two networks seperate and they do not have to talk to each other.
I have tried adding an additional interace and I could not pass any traffic to the secondary lan host. I have tried configuring Static Routes and advanced outside NAT with no sucess.
there are entries in the log that show icmp being blocked to the wan interace from the secondary lan host.
X 09:58:23.140102 LAN 192.168.72.10 xxx.xxx.xxx.xxx, type echo/0 ICMP
Any thoughts?
