Running SBS in a public IP - success!!

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi all,

A few weeks ago I posted on running my network with a set of public IP
addresses, this is not such a popular idea, but I have it now set up
and it works extreemly well, and has solved our NAT based issues.

I have it running thusly:

I have the router connected to subnet 1 (two usable addresses), and
the firewall (www.firebrick.co.uk) connected to the second address on
the first subnet. The Firebrick also uses an address on the LAN
subnet (14 usable addresses), and I have the rest of the machines on
this subnet.

I have set rules which only allow HTTP and HTTPS traffic into the SBS
box. I have a Linux gateway which runs SMTP and forwards it to the
SBS server.

My only issue was with reverse DNS lookups on the LAN - the wizard
created me a strange reverse zone which did not work - eventually as I
only had a small number of addresses I created a reverse zone for each
IP address - reverse DNS and dynamic registrations now work
floorlessly.

I realise the issues I may come into with this config, but at the
present time it is exactly what I want and is working fine. I am
never going to say I wouldn't change back, but certainly not in the
near future.

If anyone wants any more information on this, feel free to get in
touch.

Thanks.
Andrew.
