1. Neviem preco Router02 odpoveda na ping (Destination Host Unreachable) pri teste na Router01 a naopak. Moze to byt chyba v konfigu?
2. Ked nahradim napr. Mikrotik Router01 s Linksys home routerom tak vsetko funguje ako ma, ziadny packet loss alebo TCP retransmission.

Router OS 6.24, firmware 3.19
