PIX - turn off DHCP

Aug 14, 2006 2 Replies

New client wants to turn off DHCP on a pix; I assume I just say "no" to



dhcpd enable inside



or do I need to say "NO" to all ?



dhcpd address 10.0.0.100-10.0.0.150 inside dhcpd dns 10.0.1.99 dhcpd wins 10.0.1.160 dhcpd lease 3600 dhcpd ping_timeout 750



any "gotcha's" waiting for me ?

Just the enable is enough.

You should test: if you have a dhcpd address pool configured but the dhcpd is not enabled, then will the PIX detect if the pool conflicts with other addresses?

Or to save the test, explicitly deconfigure the other dhcpd items -- that's probably easier.

Clients might have a IP obtained from PIX-dhcpd. Then you enable dhcp server and disable pix-dhcpd. If your new scope overlaps, and the dhcp server is not configured to verify the IP before offering, you might end with the same IP obtained twice. But since your lease time is very low, this problem will go away over time.
