Ciao a tutti! Seguo da circa un mese il vostro forum e finalmente oggi mi iscrivo.

Ho un cisco 877 con una configurazione funzionante per una adsl telecom
con vpn intestata per comunicare con la sede.

Ora però dovrei adattarla per un fornitore di linea privato che arriva
al cisco 877 con un cavo RJ-45 invece del cavo telefonico.
E' possibile utilizzare la porta FastEthernet0 al posto della porta
ADSL?

Tra l'atro il fornitore di linea (a differenza di telecom) mi da oltre
all' IP Pubblico un Gateway da dover inserire nella configurazione e mi
raccomanda di accertarmi che il cisco supporti la connettività Broadband :!:
Dove inserisco il Gateway? (111.111.111.111)

Vi riporto la configurazione che tento di modificare.
Grazie mille per ogni risp! :D

suppongo sia fasweb..

in ogni caso metti una porta fasteth sotto una VLAN diversa e gli aggiungi l'ip con "ip addr dhcp" (se in dhcp) oppure staticamente.

ciao

Grazie intel, no il fornitore non è fast ma un privato ke si
è comprato tutte le utenze!

Essendo novello ti kiedo se ho capito bene: nel mio caso per esempio dovrei mettere la f0 sotto Vlan2
e poi assegnare alla Vlan2 l' IP Pubblico che il gestore mi ha assegnato?
E la ATM0.835 point-to-point devo modificarla?
Come potrei scriverla rispetto alla conf postasta sopra?

no.. l'ATM in teoria non ti serve...

secondo me questi arrivano direttamente in ethernet..

ovviamente ricordati di:
no ip route 0.0.0.0 0.0.0.0 ATM0.835
ip route 0.0.0.0 0.0.0.0 < gateway (111.111.111.111)>

Grazie mille, infatti continuava a non andare...
Mi faccio rimandare il cisco e poi ti posto la config prima di rispedirla!

player 09sc10zmc13sa report wow: Deadly plague hits Warcraft world A deadly virtual plague has broken out in the online game World of Warcraft. wow gold Although limited to only a few of the game's servers the numbers of characters that have fallen victim is thought to be in the thousands. Originally it was thought that the deadly digital disease was the result of a programming bug in a location only recently added to the Warcraft game. wow power leveling However, it now appears that players kicked off the plague and then kept it spreading after the first outbreak. Since its launch in November 2004, World of Warcraft (Wow) has become the most widely played massively multiplayer online (MMO) game in the world. wow gold Its creator, Blizzard, claims that now more than four million people are regular players. Last rites wow power leveling Wow is an online game that gives players the chance to adventure in the fantasy world of Azeroth that is populated by the usual mixture of humans, elves, orcs and other fantastic beasts. As players explore the world, the characters they control become more powerful as they complete quests, kill monsters and find magical items and artefacts that boost abilities. wow gold To give these powerful characters more of a challenge,wow power leveling Blizzard regularly introduces new places to explore in the online world. In the last week, it added the Zul'Gurub dungeon which gave players a chance to confront and kill the fearsome Hakkar - the god of Blood. wow gold In his death throes Hakkar hits foes with a "corrupted blood" infection that can instantly kill weaker characters. The infection was only supposed to affect those in the immediate vicinity of Hakkar's corpse but some players found a way to transfer it to other areas of the game by infecting an in-game virtual pet with it. wow power leveling This pet was then unleashed in the orc capital city of Ogrimmar and proved hugely effective as the Corrupted Blood plague spread from player to player. Although computer controlled characters did not contract the plague,wow power leveling they are said to have acted as "carriers" and infected player-controlled characters they encountered. wow news
