|> "PPoE vs. Static IP?"|
really more a comparison of Dynamic vs. Static IP as that is really the major difference here I think. Most routers now have some sort of "Keep alive option / Check Connection every x secs" built-in so the difference between logging in to authenticate or not is really negligeable.
The difference between having a dynamic IP vs. Static however is another issue. If you are using VPN, then you already know the value of a fixed IP since you use that IP to connection, right? If you change to a Dymaice IP (PPoE) connection then you will have to implement manners of acquiring your new IP whenever it changes, some options may include:
1) Using DynDNS.org or some other IP finder type program
2) Setting up BLAT to Send and email out from the system (IP address retained in the headers) or some similar situation.
You will find it more difficult to work with an always changing IP address, but it can be done and might be worth it if there is a significant cost savings.
Other issues that I have seen in relation to a changing IP address is intermitten internet connectivity loss when the ISP forces a change of the IP lease. Usually this is hardly noticeable, unless you are actively using your interenet when the lease is expired. Can cause possible issues with server based solutions.
That's my 2 cents.
Hope it helps!
