we have an ASA running 8.2.2 (adsm 6.2.5). VPN connections are working well.
But it's not possible to use a SIP client (phone or software) through an SSL tunnel.
So today I've tried to look in detail on this problem. I installed an ubuntu system,
openconnect and ekiga as softphone. In our network everything is working without
any error. I used an external DSL connection to test everything over the VPN tunnel.
I can ping the SIP server and I can access the https frontend of the the SIP Server.
The client "seem's" to connect as well. I can call the ekiga client, it's ringing and
i can speak and hear everything (most times).
Dialing from the ekiga client ALWAYS fails.
On the ASA there is no policy allowing or denying those connections.
a) How can I trace it on the ASA ?
b) Has anybody seen this behavior ? (only one way communication)
Thanks and bye, Peer
