PPPoe versus Routed Bridge?

Hi, I was having some internet connectivity issues today, and my provider suggested I use Routed Bridge mode instead of PPPoe to connect. It worked, but I'm wondering, is either any more or less "secure" than the other? I also have very strict firewall rules enabled in my router, will changing this protocol affect it any? I'm sorry, my networking knowlege is very weak.

 

I myself am not to sure of this; Might be kind of a tough Q to answer. With my limited knowledge i'll say this much...'Authentication' wise it seems PPPoE would be the obvious winner when speaking about being secure as Bridged mode doesn't require any authentication per say.

With that said, i'd like to see some answers to this Q myself.

A little reading.

 

Thanks for the reply. I haven't been able to find much yet unfortunately in the way of answers.

 

PPPOE is a historical thing that the ISP transition from modem to ADSL(in some case cable), mainly for accounting reason on their side. Nowadays, almost everyone is just using the simple approach.

As for security, you have to always assume it is 'not secure' packet wise once it get out of your own network perimeter but other than that, there is no security concern. your account now is tied to your modem directly into your house so no one can disguise as you.

so no need to worry, your line of defense starts in your router/firewall(and none of your local machine should be visible in the big internet, i.e. all local ip range say 192.168.* ) which by default doesn't relay incoming probe anyway so safe by default.
