No connection from Mac OSX 10.6 VPN to Cisco ASA 5505

By ctkmac ·
Just got an ASA 5505 to replace our old firewall/vpn device. It's a steep learning curve and I have been able to work through most of the initial issues, however this Mac VPN connection issue is leaving me stumped. When I try to connect via the built in Mac OSX 10.6 Cisco IPSec connection I get the following: "A configuration error occured. Verify your settings and try reconnecting". I can confirm that the host, pre-shared key, group name, and user name are correct. It does not even get to the point where it prompts for a password.

Using the VPN Client on Windows XP it connects without issue.

I have tried using debug crypto isakmp and debug crypto ipsec but no information is collected when attempting to connect on a Mac.

Here is the config on the ASA 5505:

Thanks, this pointed me in the right direction. Adding the lines:

crypto ipsec transform-set TRANS_ESP_3DES_SHA esp-3des esp-sha-hmac
crypto ipsec transform-set TRANS_ESP_3DES_SHA mode transport

enabled me to connect through the Cisco IP-Sec built in VPN connection. Will work on getting it to work with L2TP but it's not required.
