We have a ASA 5540 with SW Ver. 7.2(2).
If I try to connect with VPN-Client 4.8, it will work. But with VPN-Client 5 it doesn't work.
After Capturing the Inital Packets from the Client, I see only one difference. VPNC V4.8 used as Source Port UDP 500 (isakmp), while VPNC V5 used Port UDP 1501.
In the ASA Logfile I see the following message:
7 Nov 05 2007 10:47:03 710005 172.30.225.253 vpn-oedatdos UDP request discarded from 172.30.225.253/1756 to Oedatdos:vpn-oedatdos/500
As explanation I get the following text:
This message appears when the security appliance does not have a UDP server that services the UDP request.
Is this a configuration problem in the ASA, or must I upgrade on SW Ver 8.0(2)?
