Windows SBS 2003 VPN implementation

I am a VPN newbie.

Here is the setup.

SBS - Hub - Cisco pix - Cisco router - Internet connection

Currently the SBS is used as a file server to the other 15 PCs on the hub.

I want to implement a simple VPN solution.  Probably PPTP with MS-Chap v2.
Is it feasible to put a second NIC in the S.B.S. and connect it directly to the router bypassing the firewall.
Or would this be a big security risk?

Any help would be greatly appreciated.  Thank you.

THat is feasible but a Tremendous risk as you would expose yourself directly tothe internet.  YOu definietly need to have a firewall in from of all connections to the internet.  Is your Cisco router managed by your ISP?  If so is it acting as a firewall or are all ports wide open?

Thanks for the quick response.  I really appreciate the help.
I have to go through a Cisco Pix 500 series Firewall and then to a Cisco Router then to the internet

So then I guess I should make sure TCP port 1723 and GRE protocol 47 are open through both the firewall and the router.

So you think putting a Second nic in my SBS and hocking that up the firewall and making sure those ports are open would work?

Thanks again.

Yes.  You should add another NIC card to your Server hook that up to the Cisco PIX and the other NIC of course is hooked up to your internal network.  Then all you should have to do is open up the ports and then set up routing and remote access to allow VPN connections.
