I am not sure if a CIsco ASA will allow FTPS as a protocol for the clientless, possibly with port forwarding or a plug-in, I'll have to check. I need occasional transfers of large files from a vendor who will be pulling the data from an FTP server in a dmz. &nbsp;I wanted to avoid the costs of a full site-to-site VPN and was unsure of the limitations on the clientless option. &nbsp;Have you seen FTP servers configured for two factor auth? i.e. secure id token?

secure ftp

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.
