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

no route 0 0

Hope this helps,

outside route 0 0 sss.sss.sss.sss other static

inside route ddd.ddd.ddd.0 submask rrr.rrr.rrr.1 conect static

outside route xxx.xxx.xxx.xxx 255.255.255.254 sss.sss.sss.sss conect static

Re: How chang IP informaton for PIX515E

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

Re: How chang IP informaton for PIX515E

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.

Re: How chang IP informaton for PIX515E

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.

Re: How chang IP informaton for PIX515E

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.
