Multiple Public Static IPs MAC/DHCP

ArtjomN · Feb 25, 2013, 9:23 AM

Hi.
I am really new to pfsense.

I have a problem my ISP is given me 10 public ips’ on DHCP and they all assign to different mac addresses.
I can’t get any configurations from them.
They saying it is DHCP you don’t need to configure anything.

My goal is to get Multiple MAC on a single interface.
So how can I manage to get all of them on 1 nic in PFsense?

In advance then for your help

Have you tried to setup 10 interfaces with same NIC configuration?
If I remember right only in interfaces you can specify own MAC addresses (not possible in virtual interfaces).

Outgoing should be no problem because all IPs use same gateway and provider should normally decide with IP and not MAC if the package is vaild.

Hi Reiner030

Unless I am doing something wrong you will get an Error.

helps not soo much... perhaps this thread can help a little:

The "easiest" solutions could be to

add 10 individual network ports ; connect them to a local swith and so to the provider.

better:

the provider should show howto setup his environment with "default" equipment... ;)

You could buy a switch that supports vlans (a managed one) with a minimum of 11 ports.
You can buy these if its not a gigabit one pretty cheap second hand.
And than connect it to one network interface and trunk all the vlans to it.
So you have 10 virtual interfaces.
You could also try to follow this tutorial but I'm not sure if it works for you because you isp needs to route the traffic of the other nine addresses to you any way. Not sure if its so when they use dhcp.

This thread might be interesting to.
http://forum.pfsense.org/index.php/topic,3987.msg24632.html
And you can try to search for virtual ip in the forum.

Please post your solution I'm looking in to this to and have not figured it out yet.

Right now i have.

But thee is a problem i am getting kernel: arpresolve: can't allocate llinfo for 85.253.96.1

I have 3 Extra switches 24 port HP unmanageable, 24 port HP manageable and Cisco 2960G 8 Port.
So i will try Vlans i thing this week.

In what way are you connected to your isp.
Do you have a modem in half bridge that gives you the external ipadresses?

The "can't allocate llinfo" could be caused by a missing default gateway.
You could add a default gateway witch you external ipadres for the interface with the error. Maybe it wil solve your problem.

Hi,

your 1st post: youtube/forum link shows only howto add multiple IPs… but not with the special problem to assign MAC addresses to specific public IPs.
There are no configure parameters except in interfaces where you can set individual MAC adresses as I know which are needed for the setup in inital post...

@stormeporm:

The "can't allocate llinfo" could be caused by a missing default gateway.

interesting… I searched twice for this error message without success.
I have also this problem when I try Quagga OSPF routing with 2.1-BETA1 to 2.0.1 in my internal TRANSIT network between 2 firewall pairs.
Just yesterday my master firewall looses her gateway 192.168.6.1 with same error message. :-(

(Setup of transfer network:
fw-jws1: 192.168.6.1
fw1-jws1: 192.168.6.2
fw2-jws1: 192.168.6.3
fw-zws8: 192.168.6.11
fw1-zws8: 192.168.6.12
fw2-zws8: 192.168.6.13

when this problem occours fw1-jws1/fw2-jws1 can reach fw1-zws8/fw2-zws8 and other way round.
But looses the hop 192.168.6.1/192.168.6.11 ... very suspicious :(

Are somewhere further informations about this kind of message and what can be done?
The only thing I found out that "can't allocate llinfo" problem seems very BSD specific...
Thanks

Reiner

About the first post.
In what way are you connected to your provider? Is there modem giving you the ipadresses and working as a dhcp server? In what way does it connect to your provider?
I'm using a modem in full bridge mode over pppoe.
What I have running now is different external ipadress for single computers not interfaces. If I have some time I'll try if I can make it work for an interface like your setup. Something on my todo list for a long time anyway.

About the cant allocate llink, whatever I have found about it is a problem with the default gateway or default route.

I've had a problem with a modem in half bridge that was giving external ipadresses by dhcp where the gateway and the wan ipadres were not in the same subnet. Manually editing the default gateway/route solved it. Thats why I'm curious about your isp connection.
