thank you for reply, your help is greatly appreciated as you are the only one since I posted my question here( half month), and I am wondering if it's possible to use Microsoft RRAS (routing and remote access) to achive this goal? and one more thing needs to be added is ASA 5500 is acting as a VPN server. if the answer is yes, can you please provide me more details on it? hopefully it's not offending any policy here, I know I am posting question on Cisco's community.

ASA has L2tp IP sec configured, and it also provids real time VPN connetivity information, but not everyone is supposed to logon to ASA to check it out, I am wondering if there is a console (or something else) that can be installed on local machine to remote control/monitor the VPN connectivity? thanks.

user got disconnected and no luck in reconnecting back until 10 minutes later, ASA syslog shows : removing peer from correlator table failed, no match! googled the error message, "Most Common L2L and Remote Access IPsec VPN Troubleshooting Solutions" mention this: VPN tunnel fails to come up after moving configuration from PIX to ASA using the PIX/ASA configuration migration tool; these messages appear in the log: [IKEv1]: Group = x.x.x.x, IP = x.x.x.x, Stale PeerTblEntry found, removing! [IKEv1]: Group = x.x.x.x, IP = x.x.x.x, Removing peer from correlator table failed, no match! [IKEv1]: Group = x.x.x.x, IP = x.x.x.x, construct_ipsec_delete(): No SPI to identify Phase 2 SA! [IKEv1]: Group = x.x.x.x, IP = x.x.x.x, Removing peer from correlator table failed, no match! This issue happens since PIX by default is set to identify the connection as hostname where the ASA identifies as IP. In order to resolve this issue, use the crypto isakmp identity command in global configuration mode as shown below: crypto isakmp identity hostname my question is: 1. why the user got disconnected and was able to reconnect back in 10 minutes without any modification being done on ASA? 2. what does the log error mean? if similar issue happens again, should we take action at all? thanks.

what can an employee brought in? u mean a switch or an AP? we customized the SSID, how can an employee duplicate the SSIDs? doesn't make sense to me. my main concern is what sometimes devices can't connect to the AP/SSIDs, regardless the company assets or personal devices. thx.
