Problem:
mam przekierowany port 3399 z iterfejsu wan0 na lan0 na 192.168.9.100:3399
na router wskazuje domena xyz.pl
i wszystko jest pieknie jezeli lacze sie z domena xyz.pl:3399 z sieci zewnetrznej porty ladnie przekierowuje Very Happy jest bajka
ale kiedy lacze sie z sieci lokalnej (lan0) z domeny xyz.pl:3399 to otrzymuje "server connection refused"
ale jesli lacze sie z sieci lokalnej (lan0) z 192.168.9.100:3399 to dziala pieknie.
