I've tried in the past but never really had solid results for vpn
setup. I have a BEFSR41 linksys router. Would like to understand the
vpn setup process for windows 2000/xp pro configuration.
Been reading alot on the net, obtaining bits and pieces here and there
but nothing real solid.
I just setup another Windows 2003 server and tried to get the Linksys
units (three of them) to pass PPTP/GRE inbound to the server so that I
could RAS into it and never got it to work. In fact, I spent 2 hours
with the MS Networking Support Team the other night, just to find that
the Linksys units don't pass GRE outbound.
While searching on the Linksys site again, not that CISCO has take over
and change the firmware, I found an interesting article that states you
have to forward PORT 1723 BOTH to the server AND PORT 47 BOTH to the
server. GRE is not a port, it doesn't use PORT 47, but it appears that
Linksys has changed the PPTP sessions to require GRE to use PORT 47 in
their latest firmware.
I didn't confirm the above, I bought a D-Link DI-808HV unit and it
worked fine, heck, it can even act as a PPTP end-point if you want it
Someone there is confused. GRE is IP *protocol* 47, and has nothing
to do with UDP or TCP, which are two other IP protocols, and
"ports" are associated with UDP and TCP. The BEFSR41 has special
PPTP passthrough support, but, as you say, that may be for inbound
only. You might want to take this to the Linksys forum on dslreports:
Not too long ago I was considering a BEFSR41, and inquired of a friend who
has been working in the "small" network realm for many years. I present an
excerpt from one of his emails to me on the general subject of home
networking, in which he refers to his own set up.
"I went with the Linksys BEFSX41 because in addition to the hardware
firewall feature, it
also supports VPN end-point which I need for work - the nearest
competitive unit Netgear offered would only support VPN pass-thru, not
enough for my needs. $60 retail, much less than the $360 I paid for the
Webramp unit back in early 2000.
Linksys BEFSX41 review here:
When a router is used as a PPTP end-point in a peer-to-peer network, can
the remote computer access a host computer within the network? Once the
remote computer validates and connects to the router, how does that
computer access another computer behind the router, if it can?
OK, I have been setting up VPN here also... Today I succeded some what.
Connection is between 2 BEFSX41 routers.
Net A (My net) running windows 2k pro
Net B (His Net) running win XP
I get all my computers in his Network Places
Now for MCP6453 the routers all handle the security and tunneling when you
get a connection go to network properties and set up a conection for outside
computers share the files you want and operate the system as if you added a
new computer on you internal net.
I did find one Item that might be helpful... each router that does this end
point MUST be on a different subnet..
IE: router A must have an address of say 192.168.1.1
and router B must have the address of 192.168.2.1
You can set up a vpn. In fact, that's what I'm using right now. I'm
sitting on my couch, with my notebook, to access my news reader program on
my desk top system. Another thing I do, is use the vpn to send smtp mail
when I'm away from home. My notebook is configured to access my isp's smtp
server, only via the home network. This way, when connected to the
internet elsewhere, I can appear to be accessing the smtp server, from
I use OpenVPN.
I have a DSL account at my office that has access to an excellent news
provider. My RoadRunner news server accessible at home is terrible.
There is a way that I can set up a proxy server such that I can access
my office news server through my home computer. The office DSL has a
static IP. How can I access my office news server from home? I do not
want to use pcAnywere or Remote Desktop Protocol because of speed.
I know that this can be done, because a guy in
bellsouth.net.support.adsl was posting from outside BellSouth when the
newsgroup was only available if you were accessing from a BellSouth
account. He said that he had a proxy through a friend's computer that
was on BellSouth. He has not been heard from in a year, so I cannot ask
him for a better explanation.
