Protože sockstat ukazuje že je to firefox, když ho zavřu pokus o spojení okamžitě mizí.Spojení se neuskuteční protože adresy blokuje firewall,wireshark ho vůbec nevidí,mám jen pflog firewalu.Jde o to že firefox se pokouší připojit na tyhle dvě adresy a na ostatní z toho rozsahu které taky blokuju ne. Jsou to 217.75.209.210:80, 217.75.209.211:80
