   PPP jako takove multicasting podporuje, nicmene gated o tom nevi (jeho
oblibeny problem). Zkuste:

	- ifconfig ppp0 multicast   (pouze pokud mate kernel 2.0.X)

	- Zapnout pri kompilaci gateda, ze OS podporuje multicasting (mam
	  pocit, ze to v nektere z defaultnich konfiguraci bylo vypnute).

(Kdysi jsem tento problem uz vyresil, ale jednak to bylo s jakousi velice
archaickou verzi gateda, jednak uz si to presne nepamatuji...)

				Have a nice fortnight
