Do I need a VPN router to pass through the PPTP protocol?

[jamster1]

Or can I just use a normal router that supports and passes through
Microsofts default PPTP protocol. I am setting up an ADSL line on our
network so that staff can VPN into our network over the internet. I
just want to use Microsofts VPN for the moment using RAS.

Also, when routers are sold as "VPN routers", does this mean they have
their own security, server and client software, etc as opposed to using
Microsoft VPN through a normal router?

yes, you need pass through. when routers are sold as "VPN routers", it is
possible the router be setup as ipsec VPN, PPTP VPN or/and PPTP pass
through. refer to the manual.

To use a server on the LAN as the VPN server, you need to configure port
forwarding on the router (so that the VPN traffic actually gets to the
server). You also need to make sure that the firewall/router doesn't block
something which VPN needs (such as GRE for PPTP).

You usually need to read the fine print. Sometimes "VPN router" just
means it allows VPN pass-through. I think that it should mean that the
router is capable of supporting VPN on its own.

Note that if a router can support VPN directly, you can still
authenticate against your Windows database if the router/firewall supports
RADIUS. IAS, which is included in W2k/2003 Server, is a RADIUS compatible
system. The clients can connect directly to the VPN device but be
authenticated by Windows.
