Hello all,

For the W-ISP I work for, I have decieded that for security and control
we will be using either PPPoE or PPTP to give our customers access to
the internet. I have a miniature prototype setup and I like the
results. Currently using roaring penguin's pppoe-server with
freeradius I have dynamic IP's, one simulatenous session, and accounting
running flawlessly.

The computer that will run the pppoe-server or pptpd is a P4 3.0GHZ with
one gig of RAM. I plan to have three hundred PPP sessions (maximum)
connecting into this machine (is this plausable or am I dreaming?) and
pppd takes care of contacting the RADIUS server (another machine). I
like this because as soon as this system is full, we just add another.

But I want to make sure things are reliable and rock-solid. The
pppoe-server runs nicely but I know it is not meant for a production
environment. If I do use it, what would some of the reprocutions be?
Would performance be better if I were to use PopTop with no encryption?
  Is there an alternative to pppoe-server? I would like to use PPPoE
since it is widely supported and all broadband routers support it (I
know a lot of broadband routers support PPTP, but there are probably
some that don't).

Thanks in advance,
Kevin Brown.
