I'm having a strange issue with remote access VPN connectivity on our ASA cluster.
Normal site-to-site tunnels and AnyConnect connections works just fine. However, a special ipsec ikev1 tunnel does not. It establishes, and stays up, but the client (in this case an Avaya VPN Phone) does not either recieve a client address, or it doesn't ask for one (bit unsure who to blame).
This image shows the connection when it's established. Notice that the Assigned IP address is blank. Bytes TX being "0" is quite natural, as the networks on the inside have no client to route to.
I tried debugging this via ASDM, but to no luck. I'm not confident enough with the CLI to do a console debug, as we're using the "notification" keyword quite heavily to match every ACL we have.
