add extendable keyword for each command.

ip nat inside source static tcp x.x.7.42 1720 interface Loopback12 1720
extendable

Hi,

I recently replaced a 7206vxr NPE-G2 with an ASR1K and copied the
configuration.

The 7206 had the following NAT config for my callmanager  to communicate
with a VoIP provider's call controllers that I couldn't paste on the ASR:

 

ip nat inside source static tcp x.x.7.42 1720 interface Loopback12 1720

ip nat inside source static tcp x.x.7.42 4001 interface Loopback12 4001

ip nat inside source static tcp x.x.7.43 1720 interface Loopback13 1720

ip nat inside source static tcp x.x.7.43 4001 interface Loopback13 4001

 

When I try to paste this config on my new ASR1K running
asr1000rp1-adventerprisek9.03.04.02.S.151-3.S2.bin, I can configure the
first two lines which NAT the x.x.7.42 IP on ports 1720 and 4001 to the
loopback 12's address but for the next two lines I get the following
message:

"%Port 1720 is being used by system"

"%Port 4001 is being used by system"

 

| can't get my VoIP to work without this NAT.

 

Any ideas?

 

Kind regards

 

Nasir Shaikh
