- # OpenWrt Package for xl2tpd
-
- xl2tpd is a development from the original l2tpd package originally written by
- Mark Spencer, subsequently forked by Scott Balmos and David Stipp, inherited
- by Jeff McAdams, modified substantially by Jacco de Leeuw and then forked
- again by Xelerance (after it was abandoned by l2tpd.org).
-
- ## Rationale for inclusion in OpenWrt
-
- l2tpd has some serious alignment problems on RISC platforms. It also runs
- purely in userspace.
-
- Some of the features added in this fork include:
-
- 1. IPSec SA reference tracking inconjunction with openswan's IPSec transport
- mode, which adds support for multiple clients behind the same NAT router
- and multiple clients on the same internal IP behind different NAT routers.
-
- 2. Support for the pppol2tp kernel mode L2TP.
-
- 3. Alignment and endian problems resolved.

- ## UCI options
-
- `server` takes the form `host[:port]` with port defaults to `1701`. It
- specifies the l2tp server's address.
-
- `checkup_interval` tells netifd to check after that many seconds since last
- setup attempt to see if the interface is up. If not it should issue another
- teardown/setup round to retry the negotiation. This option defaults to 0 and
- netifd will not do the check and retry.
-
- The following are generic ppp options and should have the same format and
- semantics as with other ppp-related protocols. See
- [uci/network#protocol_ppp](https://wiki.openwrt.org/doc/uci/network#protocol_ppp_ppp_over_modem)
- for details.
