unknown leases, zna nekdo zavadu ?

[zubodravec]

Podle googlu je pry problem, ze klient neuznava jako autoritu nas dhcp server.Muez nekdo poradit jak zavadu odstranit ?
Nekolik lete provozujeme dhcpo a z DB si tahame zazanym aby zakaznik dsotalou pokazde stejnou adresu od dhcp serveru.
Nyni se nam obcas stane, ze na par hodinzakaznik dostane adresu z poolu pro neregistrovane a zavada sama zmizi po par hodinach, zakaznik si pak lizne spravnou adresu.
viz nize zaznam z logu.
