Lots of things, including (but not limited to):
- IP address
- DNS server IP address (up to 2)
- WINS server IP address (up to 2)
- banner
- default domain name
- split tunnel network list
- split DNS domain list
- save password feature
You can easily see what's sent by opening up the client log viewer, then start up your tunnel, then go through and look at the log, everything that the concentrator sends will be listed there in the format:
34 15:01:46.073 04/27/04 Sev=Info/5 IKE/0x63000010
MODE_CFG_REPLY: Attribute = INTERNAL_IPV4_ADDRESS: , value = 12.13.254.121
35 15:01:46.073 04/27/04 Sev=Info/5 IKE/0x63000010
MODE_CFG_REPLY: Attribute = INTERNAL_IPV4_DNS(1): , value = 12.13.200.248
36 15:01:46.073 04/27/04 Sev=Info/5 IKE/0x63000010

MODE_CFG_REPLY: Attribute = INTERNAL_IPV4_NBNS(1) (a.k.a. WINS) : , value = 12.13.193.200

MODE_CFG_REPLY: Attribute = INTERNAL_IPV4_NBNS(2) (a.k.a. WINS): , value = 12.13.235.228
39 15:01:46.073 04/27/04 Sev=Info/5 IKE/0x6300000E
MODE_CFG_REPLY: Attribute = MODECFG_UNITY_BANNER, value = Hi there

MODE_CFG_REPLY: Attribute = MODECFG_UNITY_SAVEPWD: , value = 0x00000000
To see these in the Log Viewer you will need to set all your logging levels to High first.
