PIX DHCP problem

mpalis — Fri, 21 Feb 2020 08:06:30 GMT

Hello all

I have configured a PIX 525 with 6.4 code ro DHCP but it is not providing IP addresses to the clients. Configuration is as below .

ip address inside 192.168.1.1 255.255.255.0

global (outside) 1 x.x.x.x-x.x.x.x netmask 255.255.255.192

global (outside) 1 x.x.x.x

nat (inside) 1 0.0.0.0 0.0.0.0 0 0

dhcpd address 192.168.1.29-192.168.1.32 inside

dhcpd dns x.x.x.x

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd domain x.x

dhcpd enable inside

Static clients work fine.

Any help will be appreciated

What is that dhcpd ping_timeout 750? seconds? In that case I expect that the request will time out before the pix has finished its ping check to see if the adress is in use.

Please try the default for this:

no dhcpd ping_timeout 750

For the rest, your config seems OK although it appears that you have specified a very small range indeed. Please verify that the pix has not yet assigned all four(!) adresses. (show dhcpd?)

Another possibility might be that these adresses are already in use. In that case it won't work either.
