Tak zkusil jsem předělat a vypnout DMZ na ADSLku. IP sem nastavil dle třídy B. Ano ADSL mám od T-Mobilu. Zkusil jsem to samé aplikovat na můj notebook a veřejnáip:8080 se obsah načetl. Tedy jsem jen změnil IP adresu na server eth3 kartu a tam už to nejelo. Zde výpis z tdpdump.
Výpis je připojení z 3G (T-mobile) na veřejnou IP od ADSL
