Ahoj,

snazim se propojit realnou a virtualni sit. Jedna se o soucast BP, ktera se zabyva aplikaci na simulaci site, ktera ma byt schopna komunikovat do internetu. Zkousel jsem reseni pomoci vde(http://vde.sourceforge.net/), komunikace mezi virtualnimi rozhranimi funguje, nicmene vse se odehrava na fyzickem stroji, nikam dal komunikace neprojde.

Dalsi reseni, ktere se snazim zprovoznit je pomoci zbridgovani vsech vytvorenych portu. Veskere informace, ktere jsem prozatim o problemu sehnal indikuji, ze by melo vse fungovat podle mych predstav - virtualni rozhrani pro aplikaci a fyzicke rozhrani pc si budou moci bez problemu predavat data. Prozatim se mi vsak vubec nepovedlo nasimulovat ani komunikaci simulatoru s hostitelskym pc.

Mam za to, ze problem je v tom, ze stav obou virtualnich rozhrani(tap0 a tap1), ktere jsou soucasti bridge je disabled - viz vypisy nize.

cely most by mel byt smerovan do internetu pomoci eth0, neni dulezite jake dalsi virtualni rozhrani budou uvnitr, prozatim jde o funkcnost.

jedina ma domenka prozatim je, ze na konci tap0 a tap1 chybi nejake "pripojene zarizeni", kdyz jsem odpojil kabel od eth0, port eth0 v bridgi se taktez dostal do stavu disabled.

budu vdecny za jakekoliv rady, ikdyby se melo jednat o programovani nejake c aplikace, ktera by mela simulovat zarizeni na konci.
