Chapter 4 Using PIX Firewall in SOHO Networks

Using the PIX Firewall DHCP Client

Note Do not configure the PIX Firewall with a default route when using the setroute argument

of the ip address dhcp command.

Releasing and Renewing the DHCP Lease

To view current information about the DHCP lease, enter the following command:

show ip address dhcp

To release and renew the DHCP lease from the PIX Firewall, reenter the ip address command, as

follows:

ip address outside dhcp [setroute] [retry retry_cnt]

Replace retry-cnt with the number of times the request should be issued before terminating. To clear the

DHCP default route, use the clear route static command.

Note The clear ip command can be also used to release and renew the DHCP lease, but this clears the

configuration of every PIX Firewall interface.

Monitoring and Debugging the DHCP Client

The following commands provide debugging tools for the DHCP client feature:

• debug dhcpc packet

• debug dhcpc detail

• debug dhcpc error

The PIX Firewall commands used to debug the DHCP client are described in the debug command pages

in the Cisco PIX

Firewall Command Reference. Refer to these command pages for more information.
