Hi

I have an OC300 controller with the most recent firmware release loaded.

In the office, we have 1 mail server (single lan address) and 1 web server with 4 Lan IPs on the interface to handle four different websites on port 443.  One domain controller and data server.

I have 5 useable static WAN IP's provided by the ISP. configured with the aliases on the Wan settings.configured.

There are 30 desktop PCs.

Fictitious IPs are used here.

ISP addreses:                    

1.1.1.9 (Gateway)

1.1.1.10  (assigned to Vlan and routed via switches to desktops and servers)

1.1.1.11

1.1.1.12

1.1.1.13

1.1.1.14

Lan IP Range  192.168.0.1/24

Mail server IP and ports - 192.168.0.12 ports 80/443/25/993 (Port 443 used for webmail)

Webserver - Primary IP 92.168.0.20 - website 1 / 192.168.0.21 - website 2 /192.168.0.22 - website 3/ 192.168.0.23 - website 4

Ports required on each IP address 80 / 443 / 8008 / 8080/ Port 21 (on primary IP only)

Domain controller - 192.168.0.30 (No external routing)

Data server - 192.168.0.40 (No external routing)

So where is the issue?  When selecting a port forwarding rule, select the parameters, i.e., port 80, WAN interface and first WAN IP address (Primary ISP address used for network internet browsing in this case 1.1.1.10)  and route it to, say, the email server. This works fine.

But if I select another port forwarding rule, this time select, say, WAN IP address 1.1.1.11, select port 80 and route to web server, it says it cannot create this rule as port 80 is already in use? - Its a different IP address.....

If I delete the first port forwarding rule and then create a new one, this time selecting one of the other WAN IP addresses on the WAN interface and routing to the web server only, it creates it, but the ports are not open?
