Hello, I've been using my modem in "bridged mode" for years. However, recently I've read people telling how I should switch to "router mode" , because there is built-in firewall and it's safer. My question is: Is it really necessary? I know that while bridged, your computer connects directly to the internet. I've always used a software firewall and so far, never had any problems. So is there enough reason to change? I only have one PC, no wireless. Any tips, or a list of pro and cons would be welcome.
