Windows 2003 RRAS - VPN-Dialin

Hi,

i wanted to set up a win2003 server as a dialin VPN server for internet
users to access our lan.
the server has 2 network cards. both in my lan. my gateway to the internet
is a normal router, which registers dyndns. the port 1723 is already
forwarded.

a second w2003 server is the dhcp server of my domain.

when i configure the RRAS server (as vpn dialin) my internal interface gets
no ip address.
i wondered that i dont have a PPP-Adapter in my ipconfig table - but i think
that depends on the error of my internal interface...

i searched microsoft and many websites, but didnt find anything.

any suggestions?
thank you very much in advance!
best regards

Try:

1. Install the DHCP Relay Agent on the VPN server - point it to the DHCP
server.

2. If the router has a feature called VPN passthrough, make sure this is
enabled - PPTP requires Protocol 47 as well as port 1723.

3. If the VPN server has 2 adapters on the same subnet, you may have
multiple issues including VPN problems.

Hi,
thank you very much for your support!

1. DHCP-Relay is turned on
2. Router config is ok, dosnt make any problems
3. THATS my problem. thats exactly what i have. do you know any KB or
technet articles about it? it must be a common problem, because every lan i
know stands behind a router or firewall and WAN-traffic passes through
gateways or proxys. so more or less each VPN server lies in the lan. it
would be a massive fault (in my eyes) to put the VPN server on one side
directly to the internet. i know about ias, but i prefer to relay on my
linux firewalls.

Best regards and thanks once again
