Change Inside Interface IP PIX 506E

I can't seem to change the IP of the Inside Interface or the range of the DHCP server.

When I try to change one or both I get this error:

-----------------------

[OK] hostname PIC506E

[ERR]ip address inside 172.22.210.2 255.255.255.0

Interface address is not on same subnet as

DHCP pool

[ERR]dhcpd address 172.22.210.100-172.22.210.155

inside

Address range subnet is not the same as inside

interface

[OK] write memory

-------------------------

I have tried disabling the DHCP server but I still get an error.

Our Cisco guy is overseas for a few months and I feel I must be missing something very simple.

Using Pix Device Manager 3.0(4)

PIX firewall Version 6.3(5)

Re: Change Inside Interface IP PIX 506E

first remove the DHCP pool, then reip the interface, once that is done recreate your new pool.

issue " no dhcpd address 172.22.210.100-172.22.210.155 " then change your inside interface ip.

Re: Change Inside Interface IP PIX 506E

Thanks Jorge, that was it.

PIC506E(config)# no dhcpd address 192.168.1.2-192.168.1.254 inside

PIC506E(config)# show dhcpd

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd auto_config outside

PIC506E(config)# ip address inside 172.22.210.2 255.255.255.0

PIC506E(config)# show ip address

System IP Addresses:

no ip address outside

ip address inside 172.22.210.2 255.255.255.0

Current IP Addresses:

no ip address outside

ip address inside 172.22.210.2 255.255.255.0

PIC506E(config)# dhcpd address 172.22.210.55-172.22.210.155 inside

PIC506E(config)# dhcpd enable inside

PIC506E(config)# show dhcpd

dhcpd address 172.22.210.55-172.22.210.155 inside

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd auto_config outside

dhcpd enable inside

http server enable

http 172.22.210.0 255.255.255.0 inside

Re: Change Inside Interface IP PIX 506E

Glad is resolved, after config always "write mem" to not loose config if pix reboots.

Re: Change Inside Interface IP PIX 506E

I tried that and changed the IP scheme from 192.168.1.0 to 192.168.5.0 and was unable to contact the PIX 506E. I could ping it, but could not access the PDM.

Re: Change Inside Interface IP PIX 506E

make sure the source IP you are accessing PDM from is allow in PIX for administration.

e.g

where x is your PC IP address

http 192.168.5.x 255.255.255.255 inside

telnet 192.168.5.x 255.255.255.255 inside

or allow the entire inside subnet

http 192.168.5.0 255.255.255.0 inside

telnet 192.168.5.0 255.255.255.0 inside

or allow any subnets from behind the pix

http 0.0.0.0 0.0.0.0 inside

telnet 0.0.0.0 0.0.0.0 inside

See if that works.
