I am using a cisco 501 with 3DES 10 user. I know you can set a 3DES VPN connection between 2 site, but can you use 3DES with the client VPN sofware? I am using the Cisco VPN client 4.x. Also, is IPSEC the best way to go? We are a small office and would like to gain access to the intranet securely, thanks for your help!
