RE: Cable Vs. DSL

Here in Brazil,in most cases, traffic between customers and ISP is "tunneled" by PPPoE after cable modem boot and POST. The communication between cable modems is not allowed due to the config file parameters received just after the boot. Unfortunately, the official documentation of Managing Committee (a brazilian task force that writes recommendations to Internet use) are in Portuguese. BTW, here's the link:

My question is: Is it possible to snif encapsulated traffic? I don't think so, but maybe I'm wrong...

Hi Xuehan;

My own opinion is that for a SOHO office this is generally enough of a security *product* when combined with good anti-virus software because these routers effectively create a barrier by not allowing inbound connections in their default settings. However, this does not prevent trojans using *outbound* connections from being installed via email.... But no security product can provide *enough security*. Instead. I think, it is important to combine it with awareness of social

engineering/email and virus-like trojans, etc.

Do you need help?
