Hi Mohammed,

The router is not accepting ANY of the NAT commands.

I tried just putting in 'ip nat inside source ....' and this is not working.

The only thing I can type is 'ip name-server....' there IS NO 'ip nat' command

Hey there,

Help me out here. I am finding it difficult using the feature navigator. Which IOS for the 7206 was released after the one I am currently using which will support NAT?

Go to the above link and click search by feature, then from the available features choose "NAT - Network Address Translation", and click Add then click continue, then choose your platform "7200" and choose 12.3 for the Major Release, and here you are you'll get all the IOSs that support NAT for your platform.

For this flavor of NAT (Dynamic or Static), How much is 

  • Max throughput value
  • Max number Translation per second


Thanks in advance

If I were you, I would have been using 12.3T with IP PLUS feature set as it gives you and IOS with a lot of features (BGP, NAT etc)

Hope this helps,

Please rate,

Kind Regards,

I have a 128MB flash in disk 0 on this router. Can I load the new image on the same flash and have the boot statements configured to boot off either of the images

Currently the statement reads:


boot system flash disk0:c7200-p-mz.123-20.bin

Can I change it to:


boot system flash disk0:c7200-is-mz.123-22.bin

boot system flash disk0:c7200-p-mz.123-20.bin

Yes you can use multiple boot statements, and they are executed sequentially, if one fails the other is processed, and as long as the first image is valid it will always be used.
