Dicono che i model adsl usb non rendano come un buon router… Sinceramente ho fatto i miei test, il buon vecchio pppd con iptables non lo batte nessuno. They say that the model adsl usb not make it as a good router ... Frankly, I did my test, the good old pppd with iptables not beat anyone.
I router hanno il problema della tabella di conntrack per il nat: quanto avviamo programmi maliziosetti che effettuano un paio di centinaia di connessioni in poco tempo, anche se generano effettivamente poco traffico, riempiono completamente la tabella, che ha una dimensione limitata e finita relativa alla qualità del router che abbiamo. I have a problem router table conntrack for nat: what programs start maliziosetti performing a couple of hundred connections in a short time, even if actually generate little traffic, completely fill the table, which has a limited and finite on the quality of the router we have. Il risultato è l’inutilizzo della rete mentre questi programmi sono attivi ed un penoso decadimento delle prestazioni di rete. The result is the network-use while these programs are active and a painful decay network performance.
Soluzione o ci compriamo tutti un Cisco serio o facciamo lavorare molto il nostro linux con un bel modem usb da 25 euro… Solution or we all buy a Cisco or do serious work hard on our linux with a nice usb modem from EUR 25 ...
