PPP Help - Local Address, Remote Address Subnet

Wed Apr 23, 2008 9:27 am

Hello

I was thinking about routing all my customers via pptp tunnels back to the office

When I setup their accounts do I choose 192.168.0.1(example) for the local address and 192.168.0.2, 192.168.0.3, 192.168.0.4 etc etc for each client account remote address?

What subnet does that put them on, will broadcast be a problem (500 users)

Thanks :-)

Hey,

You can use 192.168.0.1 as a Local Address,
and create an Ip Pool with ranges 192.168.0.2 - 192.168.2.254.
That should give you approximately 760 IPs to use,
under subnet mask 255.255.0.0. (Is that netmask value of /16? Someone correct me!)

A nifty advantage for using statically assigned IP addresses to each user, is that if they have some services/servers running inside their network, then it's easy to forward vertain ports to those addresses/clients. :-) Advantage of the IP Pool is that all gets done automatically, and you don't have to make IP entries for 500 users individually.

Hope that sheds some light.

dont forget that with PPP there is no broadcast or subnet, its (P)oint to (P)oint (P)rotocol. . . so your gateway doesnt even have to be on the same subnet.

Is that the same with L2TP?

I was thinking of choosing L2tp after much reading
