Francesco,

In my understanding you have a 1483-B ADSL connection for your Internet
provider (lets no deep in that issue), offcourse your ADSL modem has DHCP
resource so when you use a Windows machine.
To resume simply put the IP address of ADSL (same that Windows gain above)
in your Linux server and the gateway address (from your provider) after that
everything runs fine.

Keep in mind whatever the access method connection, the first rule is you
need to reach your VPN server and hence you need obtain a valid IP
anyhow...!!! :-)

multiple ip connections to a vpn pptp server from some pc sharing the same
ip:

i would like to try to put a vpn client pptp in order to act as vpn client
for every windows machine which would like to join the remote network
instead making the pptp connection on every pc that, as talked yesterday,
doesn't work, i think.

The situation could be the following:

VPN SERVER -----> INTERNET -----> VPN CLIENT ------> PC1, PC2, PC3, ecc.

The only thing i would like to ask: in the client network i am behing an
adsl router which masquerade traffic to the outside world; with a single
windows pptp client connection everything works fine: do you think it will
works the same if the connection comes from a linux pptp client? The latest
pptp client version, is the 1.0.2 linked in poptop.lineo.com?

Thank you again to everybody, hope a nice day!

Bye,

Francesco Collini

There is one way that is use Linux or WinNT/2000 how pptp client and make
the forwarding of packets between LAN (eth0) and VPN (eth1 - pppXXX), thus
every client can access another side over the VPN. Right???

suppose that model :

client W9x --> Linux/WNT (PPTP Client) --> (( Internet )) --> Linux VPN
server --> LAN
(192.168.0.3) --> (192.168.0.1) : (200.204.53.46) ------ (200.230.76.54) :
(192.168.2.1)

after vpn established:

(192.168.0.3) --> (192.168.0.1) :: (192.168.1.3)---- (192.168.1.2) :
(192.168.2.1) ---> LAN

The Linux or Win NT PPTP client needs forward packets from 192.168.0.0 /24
to 192.168.2.0/24 via VPN tunnel (192.168.1.0).
You still need set up your ip-up file in the /etc/ppp directory.

I think is that.

Hello,

looks like there's no way :-((

I've tried many many hours to get it working but had no success... Looks
like you need more ips. Ask your provider for a class-c-network for
vpn-connections. This should work with ripe.

Bye,
Gunther

Guther,

But in most cases we have just one valid IP to the server.
How do we do so?

give several ips to the pptp-server and let each client connect to it's
"own" server. (different server ip per client)

its so simple :-)

Betreff: [pptp-server] multiple clients from the same ip

Hello,

it some days i got this problem, and i think there is no easy way to solve
it.

I have a VPN poptop pptp server which listen on a refistered ip address.
Everything works fine; i can connect from a windows 9x/NT/2000/XP client
without any problem.

My problems start when more than one client connect to the vpn server from
the SAME ip; the gre protocol i think get lost and from two or more clients
it doesn't work.

I read in the mailing-list archive that poptop "respect" the rfc and it
cannot create more than one tunnel from the same ip.

Are there some new solutions continuing using poptop? If i put, on the
client side, a pptp-linux-client which acts as a router for the windows
client to the vpn server, do you think it should work?

Thank you in advance for your kind interest, hoping hear from you soon!
