cisco Asa 5505 IPSec vpn
I am setting up an ipsec vpn tunnel but i am getting this error when enabling the crypto isakmp enable outside
Crypto ikev1 enable outside
Ikerereceiverinit, unable to bind to port
there are no blocked ports that I am aware of.
I've never had an issue with any other setup
let me know what you think
thank you

Do you have any NAT/PAT configuration for UDP port 500 and/or 4500? If so, you will need to remove this configuration, then clear xlate, then add the crypto map to the interface.
Yep
From http://www.cisco.com/en/US/products/ps6120/products_tech_note09186a00807e0aca.shtml
You can also get this error when you enable the ISAKMP on the outside interface:
UDP: ERROR - socket <unknown> 62465 in used
ERROR: IkeReceiverInit, unable to bind to port
The cause of the error can be that the Client behind ASA/PIS gets PAT'd to udp port 500 before isakmp can be enabled on the interface. Once that PAT translation is removed (clear xlate), the isakmp is able to be enabled.
Note: Always make sure that UDP 500 and 4500 port numbers are reserved for the negotiation of ISAKMP connections with the peer.

those are the only Natting I have and they are the basic ones
here is the whole code, maybe I have been looking at it too long to find the issue
nat (inside,outside) source static NETWORK_OBJ_10.6.2.0_24 NETWORK_OBJ_10.6.2.0_24 destination static NETWORK_OBJ_10.6.2.192_26 NETWORK_OBJ_10.6.2.192_26 no-proxy-arp route-lookup

object network obj_any
nat (inside,outside) dynamic interface
here is the whole code, maybe I have been looking at it too long to find the issue

have you checked the remote site to see if there is a NAT/PAT rule configure for UDP 500 and/or 4500?
ASKER
sorry there is no VPN tunnel just a regular VPN connection using the cisco VPN client
Are all users experiencing this issue? Is this happening when connecting from a specific location? What happens if you connect from another location?
ASKER
yes all users. it just doesn't allow me to configure it without that error. I tried with the VPN IPsec wizard and I get the same error
