[FUG-BR] Relayd

[Éderson Chimbida]

Sim, ele consegue fazer a checagem por ICMP, os hosts estão OK...

Aumentei o limite de estados das tabelas no meu pf.conf:

set limit { states 50000, frags 5000 }

Parece ter resolvido pois até agora esta aguentando, quando ultrapassava os
10.000 estados que é padrão no PF o relayd fechava!
