I simply need to change Ip address but I can't

openheart

Level 1

I bought a Pix 501, in the configuration, I want to change the default inside interface ip address from 192.1.1.2 to 10.0.2.234, but each time I get an error, "Interface address is not on same subnet as DHCP pool"

So I decide to change the DHCP pool addresses and I get this error:"Address range subnet is not the same as inside interface"

So I can I force the change of those settings?

did this many times. perhaps u are not in config mode when trying to enter your changes?

To begin, your prompt should look like: pixfirewall#

Then enter the following:

conf t

no dhcpd address 192.168.1.2-192.168.1.33 inside

ip address inside 10.0.2.234 255.255.255.0

end

wr mem

This should do the job

You obviously have a defaulted pix at hand.

In the default config, a dhcp pool is created for the default inside-ip range.

To change it, remove the dhcp-pool first:

no dhcpd enable inside

no dhcpd address 192.168.1.2-192.168.1.254 inside

After that you can change the interface ip on the inside:

ip address inside 192.168.x.x 255.255.255.x

I tried your suggestion, but same problem.

Again, I need to change the default IP address to another subnet. But the Pix wont let me do it!

Some information about the config I have:

Show ip address:

show IP address

System IP Addresses:

ip address outside 199.243.183.XX 255.255.255.0

ip address inside 192.168.1.1 255.255.255.0

Current IP Addresses:

ip address outside 199.243.183.XX 255.255.255.0

ip address inside 192.168.1.1 255.255.255.0

show dhcpd

dhcpd address 192.168.1.2-192.168.1.33 inside

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd auto_config outside

I want to change the ip address(inside) with 10.0.2.234 and disable DHCPD

Thanks it works! I probably did'nt enter the right command to disable dhcpd
