ERROR: IkeReceiverInit, unable to bind to port

[ronshuster]

tyring to enable :

crypto ikev1 enable outside

  and I get :

ERROR: IkeReceiverInit, unable to bind to port

I don't have udp500\4500 used anywhere.

how can this be resolved?

Hi,

That happens because there is another service using port UDP 4500 or 500.

You can run the command "show xlate" and look for such ports.

Also, enter "clear xlate" and apply the command "crypto ikev1 enable outside".

It could be related to CSCuj23318:

ASA 9.1 enabling IKE on one interface reserves UDP 500 on ALL interfaces

HTH.

Added the bug ID.

Hi,

Saw the Bug report, but I'am still not able enable it.

ASA(config)# clear xlate
INFO: 732 xlates deleted
ASA(config)# crypto ikev1 enable outside
ERROR: IkeReceiverInit, unable to bind to port
ASA(config)#

Can you please help.

Hi, you have to be fast. I mean try to run the second immediately after the first one for minimizing the chance of those ports are binded with some other traffic.
