Inside Interface Addressing problem - PIX 506E

JDShelley — Fri, 21 Feb 2020 07:21:40 GMT

I have encountered the following problem, I cannot get the PIX "inside" interface to accept the needed IP address of 10.0.0.250 255.255.255.0 on a network I inherited. I get the following message: "Interface address is not on same subnet as dhcp pool". I get this even when DHCP is disabled in the PIX config. In frustration I have even tried the mask at 255.0.0.0 and configuring DHCP to hand out 10.0.0.x address range IPs. When trying to set DHCP to the 10.x.x.x range I get a similar message: Pool addresses not on same subnet as "inside" interface. I have reset the PIX to default settings several times during theses attempts just to get back to a clean start point. Any help or feedback would be greatly appreciated.

Jack,

You'll need to remove the dhcpd address range in order to change the IP address assigned to the interface serving as the DHCP server interface.

To do this try:

PIX(config)# no dhcpd address 192.168.1.10-192.168.1.50 inside

DHCPD disabled on inside interface because address pool is removed

Now set your inside interface ip address,

> PIX(config)# ip address inside

Save with cmd - write mem.

Hope this helps.

Thanks Jay - That was the resolution. I had evidently only tried that approach with the PDM and not CLI. Thanks Again!
