symantec 200r Problem

Ok were do I start !

I have a Netgear DG632 Router going into a Symantec 200r Firewall

Settings:-

Netgear 10.10.0.1
In the WAN setting I have set the DMZ to port 10.10.0.5

200r 10.10.1.100

In the STATIC IP settings I have :-

IP 10.10.0.5
Gateway 10.10.0.1
Virtual server :- 10.10.1.1

Server IP 10.10.1.1

So I now have the 200R connected and it is working OK I can create VPN to another site and it seem to run OK

My problem is I would like to get my IIS working, so have set this to 10.10.1.1 and if I try internal it display’s the page no problem , but if I try from home with the STATIC IP I get nothing DNS error or the page is not available

If I change the Virtual server to: - 10.10.0.5 I then get the login page of 200r ?

I have taken out the 200r and just used the Netgear router and it works fine with the static IP I get my IIS and the page.

Any idea what I need to change on the Symantec 200r ?

Thanks

Paul
