Windows XP Server Configuration

sysman

I Tried using the built in VPN server of winXP & it worked fine, but for several reasons, I would like to use openVPN instead.

I have tried setting up using several howtos that i found, but as far as the server setup is concerned, they do not explain my situation were well (and/or very simply).

My set is thus:

My lan is connected to the internet via a robust firewall/router (juniper) which has a fixed IP (say 111.222.333.444) & i have no problems doing port forwarding etc.

My lan is:
192.168.0.1 / 255.255.248/0
gateway is 192.168.7.250
All devices attached have fixed Ips (there is no dhcp server)

My openVPN server has an IP of 192.168.7.1

I wish to connect to the LAN via the openVPN server and receive one of a set of valid IPs (say 192.168.7.10-20) and, of course, other valid parameters of the LAN (netmask, gateway, DNS Servers).

So how do i configure the server file? What parameters need to be defined?
Do I have to make changes to the 'local area connection' entry for the TAP connector?
Is it possible to give a specific IP to a certain client?

Thanking you in anticipation

hi there,

for start,do you want to setup bridging scenario or routing?

each scenario needs a very different setup...

you need to understand though what the pros & cons of each scenario first.

Hi

Thanks for the prompt reply.

Routing/Bridge? [routers give ip addresses & bridges don't ????]
I suppose that i do not really understand the difference as applied to vpn - I know what i want to do:

I want to be able to sit anywhere in the world, connect to the internet & then connect to my lan & be part of that lan, with a ip that is part of that lan etc.

So I suppose that that means routing. [ correct me if i am wrong ]

thanks

hi

so who hands out ips to the clients? the vpn server or someone else on the lan. [ remember, i wrote that i do not have dhcp, but if it just a matter of me deciding what ip each client can have, then that is ok]

in routing mode openvpn acts as dhcp for the vpn clients,

in bridging mode you can also use (if any) your internal lan dhcp server..

Hi,

It seems to me that i need bridging.
I looked at the link "Ethernet Bridging" http://openvpn.net/index.php/open-source/documentation/miscellaneous/76-ethernet-bridging.html and that seems to be what i want.

I started to follow the instructions & changed the name of "Local area Connection" to "tap-bridge" then I tried to create the bridge adapter, but it says that i need 2 lan adaptors. is this correct? What Ips do I give them?

you need 2 interfaces
your LAN and openvpn's TAP adapter...

do you have only one interface?
