Hi list;
I am in the process of setting up a firewall for my internal Freebsd LAN
The network looks like this:
Internet-----[ DSL router ]----[ fbsd firewall ]----[ LAN ]
ep1 ep0
I have compiled my kernel for IPFIREWALL_VERBOSE
Added support for net interface ep1 in kernel
Enabled ipfw in the /etc/rc.conf
and I am using the 'simple' rule-set in /etc/rc.firewall to test setup
All machines (router, firewall and LAN) are on the same subnet /27
All vital services DNS, HTTP and SMTP are running on the LAN machines
My questions are:
1.) What kind of gateway or routing mechanism should I use to force
incoming packets from the Internet to arrive at ep1 and pass through the
firewall and to ep0 and to the LAN
2.) outgoing packets from LAN to pass through ep0, firewall, ep1, router
and to the Internet.
The LAN consept here is probably misleading because all machines are in
the same /27 subnet.
Thank you
Dan
