I am hoping someone with extensive Cisco SSL VPN experiences can offer
advices on Cisco SSL VPN technologies? Most of my SSL VPN experiences come
from Checkpoint Connectra and F5 Firepass technologies and their concepts
are easy to understand but not Cisco. I
am having a hard time how SSL VPN work
I understand how Clientless SSL VPN (WebVPN), Thin-Client SSL VPN (Port Forwarding)
and SSL VPN Client (SVC Full Tunnel Mode) work, or at least I think I do. Here
are some of my questions:
1) The way I understand it, clientless, thin-client and SVC are supported
in both Cisco IOS and ASA products. Is that true?
2) ASA can support SSL VPN in clustering. In other words, it can do load-sharing
the SSL VPN connections. Is load-sharing SSL VPN on Cisco IOS VPN possible?
3) What are the advantages of terminating SSL VPN on Cisco IOS versus the
advantages of terminating SSL VPN on the ASA? I know that IOS can also do
GRE/IPSec and VTI and things that ASA can not do. However, if I just use the IOS
strictly for SSL VPN, what are the advantages of using IOS versus ASA?
4) On IOS SSL VPN, where do you configure it to check on the remote host
to see if the remote has the proper Anti-virus and latestest OS patches prior
to allowing to be connected into the network? In other words, what I want to do
is this: remote hostX wants to connect, the IOS will check to see if the remote
host is a company "issue" machine. If it is, it will get SVC Full tunnel mode.
If the remote machine is a "home" machine, it will get thin-client mode. If the
remote machine is a air-port Kiosk machine, it will get WebVPN mode. How do I go
about doing it with IOS SSL VPN?
5) Last but not least, there is an option called Cisco Secure Desktop (CSD). What
is the function of CSD and how is it integrated with Clientless, thin-client and Full
Can someone shed some lights on these questions? I am not interested in links. I've
spent the past seven days looking over lot of links from Cisco but all of them are
very confusing. I am hoping some experts in this forum can shed some lights on this?
