Alias in the Firewall section is for creating placeholders for IP address.
So if you change the IP of a host, you do not have to edit all the rules
associated with the host, just edit the alias. Take a look at the note on
the Alias page.

Can you separate your IP networks to two physical networks by moving one IP
network to a separate switch/hub? Are you using managed network gear that
will allow you to create segments (I think this is the definition of VLAN)?

Subject: [m0n0wall] IP Aliases question

Hello folks,

I have 2 logical IP networks (both /24) on one physical network.
Now i want to use m0n0wall as a router for external network access.

I cannot put 2 network interfaces of the m0n0wall on the same physical
network because the FreeBSD (of course) complains about erroneous arp
replies on the other interface.

Hmm, so what can I do?
Just set up an IP Alias on one physical interface for setting up the router
interface for the second ip network?
Is this Alias thingie in the section "Firewall" the right choice?
