Will FreeS/WAN work on unusual network hardware?

IPsec is designed to work over any network that IP works over, and FreeS/WAN is intended to work over any network interface hardware that Linux supports. If you have working IP on some unusual interface — perhaps Arcnet, Token Ring, ATM or Gigabit Ethernet — then IPsec should “just work”. That said, practice is sometimes less tractable than theory. Our testing is done almost entirely on: • 10 or 100 Mbit Ethernet • ADSL or cable connections, with and without PPPoE • IEEE 802.11 wireless LANs (see below) If you have some other interface, especially an uncommon one, it is entirely possible you will get bitten either by a FreeS/WAN bug which our testing did not turn up, or by a bug in the driver that shows up only with our loads. If IP works on your interface and FreeS/WAN doesn’t, seek help on the mailing lists. Another FAQ section describes MTU problems . These are a possibility for some interfaces.
