Am făcut și tcpdump să vedem cum stau lucrurile:

Din câte văd capătul remote nu răspunde nici la router solicitation, nici
la DHCP. Nu e problemă nici de firewall (zic eu), pentru că tcpdump
capturează înainte de netfilter și aș fi văzut traficul de întoarcere
înainte de a fi dropat. Oricum, am active regulile implicite de Allow
DHCPv6, Allow ICMPv6, dar pare să fie liniște pe linie...
Setările de ppp par să fie la fel. Eu am, în schimb, o versiune ceva mai
veche...

BARRIER BREAKER (Barrier Breaker, r44065)
Alte idei? Sau întreb și la RDS?
