Pix DHCP - reserved address possible?

djones · ‎11-02-2004

Is it possible to designate reserved IP addresses (i.e. based on MAC address) when using a PIX as a DHCP server?

Hi,

As far as I know, the PIXes do not support DHCP address reservation based on MAC addresses.

Thanks,

No, this is not possible. Define for example a range from 192.168.1.1-192.168.1.200 and use 201 to 254 for static entries.

example:

dhcpd address 192.168.1.1-192.168.1.200 inside

dhcpd dns dns1 dns2

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd domain yourdomain.com

dhcpd enable inside

See reference:

Cisco PIX Firewall Command Reference, Version 6.3
