pro vpn pouzivam l2tp/ipsec. Puvodne jsem mel jako koncentrator rb1200, pak pretahl conf. do rb3011 a vse fungovalo. Nyni jsem conf. pretahl do nové rb4011 a zcela nahodile se rozpadnou vsechny ipsec tunely najednou (nekdy po nekolika hodinach, nekdy za par minut) pomuze az reboot. ros 6.46.4, ale zkousel jsem i starsi a stejny vysledek.
