Hi!

I'm having a problem with an ISR4331 regarding NAT.

I cannot make a static nat for port 5011 because it keeps reponding this:

%Port 5011 is being used by system

The show ip socket gives me this:

Proto Remote Port Local Port In Out Stat TTY OutputIF
17 255.255.255.255 68 192.168.1.254 67 0 0 2002211 0
17 10.16.214.7 514 192.168.1.254 64191 0 0 400210 0

And the show ip nat portblock dynamic global gives me this:

tcp:
8192 -9215 7168 -8191 6144 -7167 5120 -6143 4096 -5119
545 -617
udp:
8597 -9620 7573 -8596 6549 -7572 5525 -6548 4501 -5524
585 -648 512 -584

So, why can't i use the port 5011 ????

The ios is: 154-3.S5

Tkx
