Add additional prefix to network interface

[hexa]

Hi all,

i've been given administering access to pfsense 2.0.3 in production.
There are many interfaces, each in it's own network. Now we got another /24 network prefix routed to this pfsense setup (advertising it using OpenBGPD). I want this /24 network to become available on the same physical network interface where another /24 bit network already resides (also advertised via OpenBGPD).

If i go to interfaces -> $"interface name for old /24 bit network", i don't see any option to add another IP/network under "Static IP configuration". So my question is this, how can I add another IP/network to this interface?

Using console it would be easy, but it would not wise to bypass WEBGUI.

Using CARP might be an option, but because i don't have another pfsense firewall with CARP, flooding network with VRRP advertisements seems stupid.

Huh 2 networks on same interface…
Sounds like VLAN to me :)

I'm familiar with 802.1q, but in this case, the costumer doesn't want to implement VLANs.

Think of it as basic IP aliasing, except on a different subnet. FreeBSD users should understand something like this:
ifconfig_em0_alias0="inet y.y.y.1 netmask 255.255.255.0"
is what i want.

OK then :)

See attached image, maybe will help :)

BTW, why not VLAN?

Looks like you should use a virtual IP of type 'IP alias'.
Look in Firewall: Virtual IPs:

Yeah sorry, you are correct…
I have wrong radio button selected in upper screenshot... It should be first one IP alias as  Stephen said :)

Thank you both / hvala.

I will try and use IP alias.

Sure thing :)

P.S.
You should really upgrade to 2.1 :)
