Your version of ppp.conf is very similar to mine. I don't have LAN here, but only one box with FreeBSD connected to the outside world through my ADSL modem. So ' set nat' and ' set proxy' options are not required in my case. I don't use ' set ifaddr' option because default arguments of it are good for me. I think that the source of my problem isn't in ppp.conf probably, but somewhere in TCP. Nobody answered me how MTU == MRU == 1484 solves my problem. Maybe there is a bug in TCP when MTU and MRU have some unstandard value. When I use Win98SE in the same box and the same ADSL modem with RASPPPOE driver of PPPoE I have no troubles when the MTU is 1492 there. This is why I think the source of the problem is in TCP implementation of FreeBSD. ppp have some dial with TCP, so maybe the source of the problem is there but most likely not in ppp.conf __________________________________________________ Do you Yahoo!?
