Hi,

One of our offices is using RAS dialup into a Small Business Server 2000.
Problems include connection dropping, failing to call back and limited to the 2 ISDN channels for 5 staff.  Also problems copying files to local computer.

Router

Switch

SBS2000, Workstations

RAS

I am considering changing this as follows as well as upgrade to SBS 2003

Router

VPN Firewall

Switch

SBS2000, Workstations

Users will connect mainly via ISP dialup but hopefully later broadband, and need to authenticate onto active directory to have their home drive mapped.

Considering one of the Cisco PIX firewalls and the following setup.

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00800b6099.shtml

Is this the best way to do this and if so, which PIX or other hardware offer the best value for money.  There are currently 5 users.  Not sure if this is likely to increase in the near future at least.

Any advice appreciated.

Jess

With so few users, you would be fine with PIX-501-50-BUN-K9.

Sorry, hit 'Submit' too fast.   Wanted to add that Cisco is the gold standard for Network hardware in a business environment.   You could use Netgear, Linksys, D-link, Sonicwall and many other excellent products, but there are more engineers familiar with the Cisco products than any other. The PIX-501 bundle includes licensing for 50 users.  So you have more than enough growth capability.

Thanks rickhobbs

Are you aware of any problems with the AD remote authentication using the client software with the 501?
Probably the following would be the best configuration using the PIX DMZ.

ADSL Router

VPN Firewall

SBS2003 ISA 2004

None at all.  It is easy to setup and maintain the VPN for either group or individual user access.

As for the config, you can:

ADSL Router
  |
VPN Firewall
  |
SBS2003 ISA 2004
  |
Switch
  |
Workstations

or

ADSL Router
  |
VPN Firewall
  |
Switch-----------------------------
 |                                           |
SBS2003 ISA 2004             Workstations

Either will work fine.  If you have daul LAN cards in the server, either use the first or, if possible, team the NICs and use the second.

Thanks Rick,

Have never considered teaming network cards before.
Is there a security benefit or just performance increase?

Performance and failover.  If one fails, the other should keep working.
