Remove the current default route before you add the new one.

Hope this helps,

The last two routes are added automatically by the PIX software and represent the locally connected subnets. No need to touch those.


you should change the ip address of the outside interface with the new address assigned by the provider using the following command:


ip address outside


and change the static default route to point to the new address on the provider side.


no route outside 0 0

route outside 0 0


Hope this helps,

that's great.Thanks.


I still have a problem, after i changed IP and default gateway.

i.e. i setup new IP as 1.1.1.1 and new gateway is 2.2.2.2.


then i run

#show route


outside 2.2.2.XXX(wrong IP) 1.1.1.1 connect static


i do not what this wrong IP is. How can it come. I did not setup it.

  • Cisco Employee,

This route you are seeing is automatically generated from the "ip address outside " command you entered. So there must be something wrong with the information you use on this command.


Can you please let us know what command you entered to get that result.


Thanks,

yes, that's the problem could be. i do not aware what the other guy do the details on the PIX.I be told the guy did below actions,


ip address outside

no route 0 0

router outside 0 0


But according your question, if the guy did "ip address outside " command, how to remove it.I ever try type "no ip address outside " but failed.
