I have a Soekris box with 4 wm interfaces. It is setup as a firewall with the following configuration.
wm0 - Outside Interface 10.0.0.254/24 wm1 - Inside Interface 192.168.0.0/24 wm2 - VLAN interface vlan0 - attached to wm2 192.168.5.0/24 My issue is I need to restrict traffic from the 192.168.0.0/24 network to and from the 192.168.5.0/24 network. I would like to use IPFilter to do this but am having trouble getting it to work. IPNAT allows the 0/24 and 5/24 network out to the internet, but if I try any rules restricting traffic from wm1 to vlan0 or wm2 it breaks internet access for the VLAN’d network. Any help would be greatly appreciated as to the correct way to limit the traffic between the two interfaces. Thank you in advance. Phil Schilling
