Hello experts

We are currently in the migration of our Exchange 2007 server to 2013. Part of the coexistence setup is to have another WAN IP address communicating with our network.

Basically, requests to IP 1.1.1.1 using HTTPs port will go to Exchange 2007 box, and requests to IP 1.1.1.2 using HTTPs port will go to Exchange 2013 box.

Is it possible with a Sonicwall NSA240?

I tried to setup the 2nd static IP on the X8 port, but it says: Error: Index of the interface.: Subnet on this interface overlaps with another interface

Thanks for the help,

Sebastien

Yes this is possible. Are both incoming ips from the same ISP? Or different ISPs and therefore different cables?

Yes same ISP. We have 4 public IP addresses with them, 2 of them are unused.

any decent firewall does support NAT you should be able to setup multiple entries.
If the packets are delivered to you then you can pass them on.

all you do is run the public server wizard. As long as your wan is setup correctly with the right mask you can use any of your public ip addresses.
Personally I leave one for the sonicwall and use the rest for forwards to servers.

After the wizard it will make a address object for the services. Just add to that service group whatever ports you need.
