SBS 2003 + VPN 1

[LordGarf]

Hi all,

I installed an SBS 2003 standard server. I use 1 LAN port on this server that is plugged in to a switch. there is also a router wich is plugged into the switch also and it has a WAN port wich is connected to ADSL.

my sbs2003 is the DHCP server so on my router it is disabled.
My router has a fixed IP of 192.168.0.2 and my server 192.168.0.1 my dhcp range goes from 192.168.0.100 to 192.168.0.200

I created virtual servers on my router so that internet connections will be forwared to the server.
I opened the folowing ports.
80 443 444 4125 and 1723
all forwared to 192.168.0.1

everything works fine. I can go to any computer with internetconnection. type my domain/remote and download the vpn client or check my e-mail with webaccess. But when I try to connect with the vpn client I get error 800 can't establish a connection.

Mostly it means that my router blocks it so I made my sbs2003 server the DMZ host. Wich means everything is open. but still nothing.

What could be the problem?

Tanks in advance

You will also want to open port 123 TCP/UDP as this is what is used for the Time Service.

VPN uses 1723 AND IP type 47 GRE.

On the SBS box make sure you re-run the Connect to the Internet Wizard located in the SBS ToDo List. There you can specify to use the server for VPN and the Wizard should configure the access for you.

I hope you find this post helpful.

Hi Mark

Tank you for your answer but VPN works localy. I ran the connect to the internet wizard succesfully.

I think that the problem relay's on the router I use.

I opened up port 1723 but I can't figure out a way to open IP type 47GRE. The support helpdesk of the router told me it was capable of forwarding it standard if 1723 whas open but after a few tests they told me to firmware my router and after that they asked me to use their router as a bridge and use SBS for internet sharing so use both lan ports.

but Then I need to use ISA on it to ofcource and I rather like HW firewalls.

So probably I need some other router.

Anyone knows of good low budget ADSL routers that can handle SBS2003 type VPN?

Tanks in advance.

If you have ISA from SBS Premium you should use that. Remember it is ICSA certified!
