ShrewSoft VPN Client

The Shrew Soft VPN Client is a free IPsec Remote Access VPN Client for both Windows 2000, XP, Vista and Windows 7 operating systems ( x86 and amd64 versions ) and for FreeBSD, NetBSD and Linux based operating systems. It was originally developed to provide secure communications between mobile Windows hosts and open source VPN gateways that utilize standards compliant software such as ipsec-tools, OpenSWAN, FreeSWAN, StrongSWAN, isakmpd. It now offers many of the advanced features only found in expensive commercial software solutions and provides compatibility for VPN appliances produced by vendors such as Cisco, Juniper, Checkpoint, Fortinet, Netgear, Linksys, Zywall and many others. The Linux version supports most of the features availalble in the Windows VPN Client version with the exception of those which are not cross platform compatible.
