Re: SBS remote connection. Urgently need some help

If you have 2 NICs in your server but are only using 1, then ISA 2000/2004
is only operating in cache mode and not as a firewall. A 2 NIC setup allows
you to put ISA in firewall mode ad get the added security benefits of ISA.

You may want to update the firmware on the router (current version appears
to be 1.02.04 which fixed a problem with VPN passthrough)
http://kbserver.netgear.com/release_notes/D102796.asp

GRE Protocol 47... The DG834GT claims to support PPTP Passthrough.
However, I see nothing in the router relating to setting this up. Not sure
what to tell you about this. You may need to contact Netgear.

And the DG834GT apparently only allows 1 PPTP passthrough sessions at a
time...

SBS 2003 SP1
SBS 2003 premium, with SP and fully updated to today.

ISA 2000 or ISA 2004
2004

2 NICs in the SBS server?
hum.. ? this is the only part of the setup im not clear on. Having never
needed to use remote access or sbs until recently ive only ever needed an
internet connection from the server before. The setup is basically, ISP
(static IP) Modem/router --> Network Hub --> Server and clients. All on
the
same IP range.
This area is a little confusing as far as im concerned. Some clarification
of how to check internal and external nic's would probably be useful.

SBS server handling DHCP for the network?
Using SBS DHCP, although all of the local network computers have static ip
addresses assigned

Port 1723 and GRE Protocol forwarded (PPTP Passthrough) to external NIC
on
SBS server?
Refer back to the 2 NIC question.(although the router settings themselves
clearly show port 1723 forwarded to the server IP)
GRE protocol? still have no idea where to find any reference to that on
our
router setting.

Network configured per the following diagram...
http://www.smallbizserver.net/Articles/tabid/266/articleType/ArticleView/articleId/76/Two-Nics-a-static-IP-address-ISA-router.aspx
Clearly not.... hum?

All connections are wired (not wireless)?
WIRED

Any errors in the event logs for the remote computer and/or the server?
NO


Can you VPN into the SBS server if you plug a laptop or spare workstation
into a port on the router and give it a static IP address in the same
subnet
as the router, then give it the default gateway of the router?
Will check this out today.

Please post an ipconfig /all for the SBS server?

Win XP remote client computer ---> SBS server premium.
Both connected to the internet through NETGEAR DG834GT router/adsl
modem/vpn/firewall.
The server is setup for remote VPN access. The client computer AND user
are
registered in the users/computers/groups as Administrator and in remote
access policy.
A connection disk was created using SBS and installed on the remote
client.
The connection does not connect. says the server is not available or
security settings are incorrect.
Have turned off all security, firewalls (with the exception of the
netgear
router firewall, which has been set to minimum security, DOS off etc
and
always allow incoming VPN) STILL no connection.
Brought the remote computer to the server and connected dierectly
through
the lan, started the remote connection software on the client and
immediately
got the remote log in screen. Told SBS to directly install all the
software
for remote access again (just to be sure) everything still works fine
locally.
Removed the client back to its remote location and the connection fails
again.
Im assuming this is a security/firewall/router issue but im not sure.
Ive
used the SBS admin companion book to the letter without success, the
SBS
user
guide without success, and downloaded many topics from this site from
other
users, all without success.
I am really stuck. And it is really important I get this connection
working.
All help would be appreciated.
T.
