strongSwan is an OpenSource IPsec solution for the Linux operating system
and currently supports the following features:
- * runs both on Linux 2.4 (KLIPS) and Linux 2.6 (native IPsec) kernels.
+ * runs on Linux 2.6 (native IPsec) kernels.
* strong 3DES, AES, Serpent, Twofish, or Blowfish encryption.
and can be used when the following prerequisites are fulfilled:
- - Linux 2.4.x kernel, KLIPS IPsec stack, and arbitrary iptables version.
- Filtering of tunneled traffic is based on ipsecN interfaces.
-
- Linux 2.6.16 kernel or newer, native NETKEY IPsec stack, and
iptables-1.3.5 or newer. Filtering of tunneled traffic is based on
IPsec policy matching rules.
