I have a cisco ASA 5520 7.0(2) and have setup the VPN client to use an IAS radius server. I followed the cisco manual for setting this up and I have kept it simple, I can see no obvious problems with the configuration however I am having difficulty getting clients connected.
I am using two test devices at the moment which are both using the same external broadband connection.
Device 1 is an Apple IPOD using the builtin Cisco VPN Client
Device 2 is a HP laptop using the Windows Cisco VPN Client 5.0.03
Device 1 can connect to the VPN first time everytime, all resources on the protected network are accessible and all activity is shown on the IAS servers logs. This device works perfectly fine from all internet connections.
Device 2 can connect to the firewall and establish a VPN connection, however 9 times out of 10 it does not receive a dhcp lease and no traffic can be received, traffic appears to only flow in one direction.
On the occasions that Device 2 does get a working VPN connection i.e traffic flows in both directions, I can access all network resources on the protected LAN, BUT nothing appears in the IAS server logs showing that any authentication has taken place.
I have replaced Device 2 with a number of different makes and models of laptops and VPN client software and all exhibit the same problem as Device 2.
What I dont understand is how device 2 is managing to gain access and authenticating when the authentication server shows no trace, and why 9 times out of 10 after authentication traffic is only one way. Yet Device1 works first time everytime using all the same settings.
I am totally baffled so any help is appreciated,
