Deactivate DHCP configuration on Cisco Pix 506E firewall

[Boniface Chiwenda_1]

Hi everyone

Iam acutally configuring Pix firewall to allocate static ip address inside.

when I check the configuration on firewall the DHCP is enabled.

The outside configuration is working well.
after issuing this command.
ip address outside 10.10.1.1
but when setting up the inside ip address it is coming up with this message.

interface address is not on same subnet as DHCP pool.
Since the default id address under DHCP are different from the one Iam trying to insert.

May some one help me on how to remove the DHCP setup or replace the default IP address with the ones we use.

Regards

Bonnie.

Hi,

I can't quite remember but try something like :

No service dhcp

If not, you can remove the default IP DHCP Pool by issuing the NO version of the command e.g :

ip local pool [pool_name] w.x.y.z w.x.y.z

Thanks Jonathan and Muhammed
for your assistance this is the command I used to disable the dhcp.

no DHCPD address 192.168.1.2-192.168.1.254 inside

This has actually worked.

no dhcpd enable is the correct command to disable dhcp server on a PIX 506.

The link below defines how to configure dhcp server on a PIX 506 if you are interested in using it however the firewalls primary function is to secure your network. If you have a DHCP server on the network I'd recommend letting it do it's job and letting the firewall do what it is designed to do.

I thought maybe I'd paste in the correct link to the Cisco commands for DHCPD configuration.
