[SOLVED] Removing cisco rules

Hello All,

I am at a loss as to how I remove a couple of lines from a cisco running-config:

when running: show running-config:

Code:

no ip http server
no ip http secure-server
ip nat inside source list NAT interface FastEthernet0 overload
ip nat inside source static 10.0.2.8 203.???.???.???
ip nat inside source static 10.0.2.4 203.???.???.???
ip nat inside source static 10.0.2.7 203.???.???.???
ip nat inside source static 10.0.2.5 203.???.???.???
ip nat inside source static 10.0.2.36 203.???.???.???
ip nat inside source static 10.0.2.6 203.???.???.???
ip nat inside source static 10.0.2.9 203.???.???.???
ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 80 extendable
ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 548 extendable
ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 8080 extendable
ip nat inside source static 10.0.2.160 203.???.???.???

ip nat inside source static tcp 10.0.2.11 548 203.???.???.??? 548 extendable
ip nat inside source static tcp 10.0.2.11 548 203.???.???.??? 8080 extendable
ip nat inside source static 10.0.2.11 203.???.???.???
ip nat inside source static tcp 10.0.2.2 548 203.???.???.??? 80 extendable
ip nat inside source static tcp 10.0.2.2 548 203.???.???.??? 548 extendable
ip nat inside source static tcp 10.0.2.2 548 203.???.???.??? 8080 extendable
ip nat inside source static 10.0.2.2 203.???.???.???
ip nat inside source static 10.0.2.3 203.???.???.???

I would like to remove the following lines:

Code:

ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 80 extendable
ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 548 extendable
ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 8080 extendable
ip nat inside source static 10.0.2.160 203.???.???.???
ip nat inside source static tcp 10.0.2.11 548 203.???.???.??? 80 extendable
ip nat inside source static tcp 10.0.2.11 548 203.???.???.??? 548 extendable
ip nat inside source static tcp 10.0.2.11 548 203.???.???.??? 8080 extendable
ip nat inside source static 10.0.2.11 203.???.???.???

I have tried saving the config removing the lines then loading the config file again, but it still does not remove the expected lines. Is there a way to just delete those 8 lines?

Cheers,

The normal way to remove a Cisco config setting is to prefix the command with "no"

With the commands you have you would need to type out the entire command with "no" on the front of each line as your removing specific rules.

Also something you may have overlooked is that the config you need to overwrite is called startup-config not running-config. Whenever you change a config setting you alter running-config but not startup-config.

startup-config is the config saved into flash and loaded on startup and then becomes running-config.

The correct way to update startup-config is to execute "copy running startup" on the Cisco CLI which will then copy running-config into startup-config

Hey, cheers for the response. I have tried using 'no' to no avail unfortunately, I have no idea why this is:

Code:

TB_BB_Package#no ip nat inside source static tcp 10.0.2.160 548 203.???.???.??? 80 extendable
                 ^
 Invalid input detected at '^' marker.

Thanks again,
