PPPoE vs Static ip

March 6, 2006 at 09:12:01
Specs: xp, 2.8/ 512

I have my own company network with VPN access and all and my ISP wants to put me to PPPoE instead of keeping static IP addressing. Should I go with PPPoE or static, what are the advantages in staying on static or going to PPPoE?

Soon I will have a couple servers one is a DC and the other one will be a firewall server would i keep static for that or put PPPoE and why?

I am confused with this thread. Do you really have a choice over what your ISP tells you?

Since it's a business, I would stick with a static IP. Normally, a basic package with DHCP is cheaper than a static IP but since you're running a VPN the last thing you need is for the IP to change regularly.

You should be running a private IP addressing scheme internally with a NAT device (preferably one that has a firewall as well) between your LAN and the WAN.

the same thing is up here my modem (and many others)is still static but sympatico want's everyone to go PPPoE they still allow me to keep my present connection the way it is(and I obviously like thing's just the way they are I don't like having to run their software and ask ,then wait for my connection to be established then if I wait too long to get back to my system I would have to re-sign in I know there are heartbeat program's that will keep my connection alive but ...)

> "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!
