lwIP builds if PPP_SERVER is enabled, meaning the auth layer and PAP/CHAP(MD5+MS)/EAP sub-layers probably work, I previously ported all the code enclosed by PPP_SERVER ifdef to lwIP, this is obviously not tested at all. However, some work is still required to add a way to get logins and passwords for authenticating clients. pppd code using /etc/ppp/pap-secrets and /etc/ppp/chap-secrets is obviously disabled. There is some malloc() to fix IIRC and probably other Linux/POSIX-calls which should be removed/reimplemented as well. At last, but not least, work is required to add passive interface support to PPP itself (in our ppp.c) and PPP sub layers, HDLC-like framing for PPPoS, Ethernet for PPPoE and UDP for PPPoL2TP. (PPPOE_SERVER is one of them). Sylvain
