using mac address to recieve a static address from pix ip pool
Hi All,
I have a pix 501 which is giving out dhcp address to the inside interface, vpn client connections and outside interface is also getting a dhcp address from ISP. My setup is 1 - 3 pcs on the inside interface which are using wireless, these are connect to a netgear wireless access point which sends the request on to the pix for a IP address. I would like 1 pc to receive a static IP based on the pc mac address.
The question is HOW, do i need to set up another iplocal pool. not sure. My config looks like this

So DHCP for clients inide is : dhcpd address 192.168.1.4-192.168.1.15 inside

Hi Batry,
Thanks for the quick reply, If no one proves different by tomorrow I will accept your answer. Is this possible on a small ASA running 7.x IOS version.

Ok Thanks, yeah thats the solution I have set up in work backend windows server. using dhcp reservation. This config is just home config for testing purposes. Pity as i didnt want to set a dhcp server at home :-( anyways thx.
I feel your pain...I would love to be able to do this as well...c'est la vie...
However, there is a workaround for VPN users. You can define a local pool for the VPN users that consists of only one IP address, then associate that pool with a specific VPN group and then give that VPN group out to individual users. For example:
ip local pool vpnpool 192.168.12.1-192.168.12.1 netmask 255.255.255.0
vpngroup user1 address-pool vpnpool
vpngroup user1 split-tunnel intovpn
vpngroup user1 idle-time 1800
vpngroup user1 password ******
You would then configure a certain VPN user's VPN profile to user the group name "user1" and they would receive 192.168.12.1 when connected to a VPN session. You could then have a separate set of commands like below to issue 192.168.12.2 to "user2":
ip local pool vpnpool2 192.168.12.2-192.168.12.2 netmask 255.255.255.0
vpngroup user2 address-pool vpnpool2
vpngroup user2 split-tunnel intovpn
vpngroup user2 idle-time 1800
vpngroup user2 password ******
However, I've never seen or figured out a workaround for assigning static IP's via DHCP from the PIX on the inside or other interfaces. :(
