VPN client not passing traffic

[markwateridge]

Ive set up a RA connection from a laptop running the Cisco VPN client to an ASA 5510, using IPsec over UDP (port 7715). The tunnel sets up, but no traffic will pass over it. Checking the stats at both ends, I see traffic encrypted by the client, but there is no increase in the decrypt counters on the ASA. I'm also seeing the following error messages in the logs :-

7|Jan 22 2007|09:35:52|710005|217.x.x.x|164.x.x.x|UDP request discarded from 217.x.x.x/7715 to External_Interface:164.x.x.x/7715

Any ideas ? I do have an ACL on the external interface to allow UDP traffic on port 7715.

The following has to be done to recover from the issue

1. Remove the following

crypto dynamic-map store match address outside_cryptomap_< number>

and had to add the following config

nat (outside) x.x.x.x 255.255.0.0

global (outside) interface
