OK, I have just built and installed ppp-020311 on my 4.2 box, but it seems not to make any difference -- nothing works, even from the ppp host, unless I also run tcpmssd. In case I've done something wrong, here are all the relevant lines from my ppp.conf (with auth data disguised): my-label: set device PPPoE:xl0 set authname xxxxxxx set authkey yyyyyyy set speed sync enable lqr set cd 5 set dial set login set redial 0 0 set ifaddr 203.143.238.93 0.0.0.0/0 add default HISADDR set timeout 0 default: set log Phase Chat IPCP CCP tun command Have I done something wrong here, or is there further info needed to answer that?
