Titolo: Conf IP Statico in Bridge Mode

Un saluto a tutta a lista, vacanzieri compresi, ho questo problema: linea 
adsl con un solo ip statico, il gestore mi dice che è configurata lato 
centrale in bridge mode, e questo mi spiazza un po' visto che le ho sempre 
configurate in rfc1483 con aal5snap o in ppp, nella classica configurazione 
che vi posto non va' bene l'encapsulation, nel sito cisco ho trovato una 
marea di documenti ma francamente è la prima volta che devo configurare un 
cisco in questa modalita' e non capisco quali siano le modifiche necessarie, 
forse e il periodo troppo caldo, forse le ferie che non arrivano, mi sono un 
po' impantanato e chiedo umilmente scusa vorrei una vs. dritta questa e la 
conf che vorrei modificare:

Grazie a tutti

La modalità 'bridge' fa sempre riferimento alla rfc 1483 e l'incapsulamento 
aal5snap va bene.
In questo caso occorre disabilitare il routing, prova a dare un'occhiata qui

Grazie del link, dopo ulteriori prove mi hanno suggerito di modificare
l'incapsulamento da aal5snap a aal5mux.
