PPPoE and DHCP concern.

Recommended Posts

Why is everyone wanting to get rid of the PPPoE ? I don't quite know what it is. I thought I read that PPPoE is a static IP while DHCP is  dynamic. Everyone keeps praying for DCHP and im told that it will slow speed down because it will share the net with other users in the area and when high bandwidth is being used in your area it will slow you down. While im told PPPoE is a very strong connection directly to the provider and you will not lose speeds. What am I missing here?

it wont affect your speed, atleast not negative

with PPPoE your MTU is 1492 and with DHCP you will get a MTU of 1500, so in theory you should be able to go faster with DHCP

however, the diff in 8 byte is almost nothing and you wont notice any diff in speed

ampz the reason most people don't likes PPPoE is because, when DSL was first introduced you had to enter your username and password when you first got on your computer to get on the internet. So it was like you were back on 56K dialup. Now what HaloBox said is not true, PPPoE is more secure because it requires a user name and password to use the internet where as DHCP does not required to have a username and password. for example i have adelphia HSI and i can take my cable modem and go anyware in the world and use it as long as im on a adelphia system. you can do this because the mac ID and SN# are stored in a database at the global CMTS, since cable has no distance problem, where as with PPPoE system there is a DSLAM every 18500ft so your mac id and SN# can't be stored at a global system like with DHCP. Also DHCP Is shared so you and you neighbor are on the same line, as with PPPoE you on a dedicated Phone or Fiber line so the internet signal will only work at the specified address at the DSLAM.

I said it was insecure because I don't like my ID and password going across the wire unencrypted.

i dont like PPPoE because when i would set up linux boxes it asked for all this info that i did not like to get, and half the time it wouldnt work because well just it didnt lol - i MUCH rather prefer DHCP..you keep your IP longer in DHCP (which i like for doin something wit servers) and in PPPoE it changed everytime u log in :

True PPPoE changes your IP address everytime you log on with it, BUT, if you just use a router to connect PPPoE to the FIOS connection, then the connection is "always on" and logged in.  You can DHCP your internal IPs to your machines, from the router.  I had the same IP address for almost a month, because my router was always on, and kept me "logged in".  It only changed because I changed some settings on the router which required it to restart, thus getting me a new ip from re logging on.

With that said though, I too prefer DHCP to PPPoE, for a couple of reasons.  First, DHCP has less overhead, due to no auth info on the packets.  Second, it eliminates the "screaming ONT" problem that many people have faced (I have not).

When all is said and done, I would pick DHCP over PPPoE.  However, it is not always the case that with DHCP you will have an IP address longer than with PPPoE.

you can avoid the "screamer" by NOT pluggin in a defaut DHCP enabled router ie one you used for cable.

ALSO you can avoid it by NOT pluggin in your computer directly into the wall. More often then not those will cause it, least from my calls i have gotten.
