I was told by an IT guy that "we now use the new "Cisco AnyConnect" and therefore you have to install that on your computer if you want your VPN to work." However, I have previously used Linux vpnc (I have version 0.5.3r449-5.1) to make a Cisco VPN connection with no problems but that I think was for the older Cisco client.
I really don't want an outside source poking around on my development computer (I do all my own IT on my LAN) so my questions are:
1) Does the AnyConnect really work so differently that I won't be able to connect without it?
2) And if not, what settings do I need in a VPN client to work like this new client?
To mimic the old client I used the following settings in vpnc:
Encryption: Secure (other options were weak and none)
NAT Traversal: NAT-T (other options were: Cisco UDP & disabled)
Disable Dead Peer Detection: disabled
IPv4 Method: Automatic (VPN), (other options: Automatic (VPN) address only)
