conf e firewall per 97

[ciscouser]

Ho da poco montato questo soho97 e sono molto niubbo, ho configurato un po' di cose leggendo in giro, ma non ho idea di come si imposti il firewall.

Ho una tin 4Mb, su "ip domain name" cosa ci devo mettere?

"access-list 100 permit..." cosa significa il numero 100 e chi lo decide?

Sono un paio di volte che la mattina lo trovo bloccato, le lucine adsl lampeggiano veloci e la CD è spenta, è stato emule?
