RWW help needed - 28.Jun.2008 5:38:48 AM

Hi, I've done a search on here already but can't find anything relevant.

I've just bought SBS 2003 R2 Premium for my company. I've installed everything and done all the windows updates. I am by no means a network admin! I know a little from working on client PCs (we're mainly software support) so bear with me while I try and explain.

My network looks like this:

Internet > Router/Firewall > Switch > LAN1 > SBS > LAN2

Basically, I've created a LAN within a LAN while I configure SBS without causing disruption to everyone else when it needs rebooting. I have one PC connected to LAN2. SBS has 2 NICS.

I ran the internet config wizard and my firewall automatically put the server into the DMZ allowing all traffic to come in to it. I can access the internet from both the server and the client.

When I ran the wizard, I enabled RWW and it created a rule opening port 4125.

I can RDP in from LAN1 and from home so I'm getting through both my firewalls on port 3389. I can't access RWW from LAN1 or from home. I modifed the defaultr.htm so I could detect that the blockage was coming from ISA and not my main firewall. All traffic is definitely coming through the firewall and getting blocked by ISA.

When I monitor the traffic and attempt to use RWW, it is being blocked by the default rule (rule 19) rather than the RWW rule (rule 3).

I've tried deleting the rule and recreating the rule. It's set up like this:

From external to localhost on a protocol that allows TCP 4125 outbound. I tried changing to inbound but without much luck.

I've searched all over the web and everyone says it's down to these ports, I opened 443 on this rule also but that didn't help.

Where could I possibly be going wrong?

Oh also, I setup a certificate to be DNS name remote.mydomainname.com which I have forwarded on to the external IP 81.x.x.x. My firewall dishes out DHCP on the 192.168.1.x range so my ISP NIC has an IP of 81.x.x.x with default gateway 192.168.1.254. Internal NIC is on 192.168.16.x and clients have a gateway pointing to the server. Would any of this be making a difference?
