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:

Edit: Beat me to it! ::)

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 :)
