We have a hotel client that has a TZ-100 configured to use their existing internet connection to support their internal business network (one subnet, SBS 2011) as well as their Reservations Webserver (different subnet, Windows 7). The internet connection has a static IP address which is being utilized by the Reservations Webserver for HTTP and HTTPS access. There are also firewall rules in place with allow traffic to flow between the two subnets over specific ports so the Reservations Webserver can communicate with their Property Management Software running on the SBS 2011 server.

They have now added another internet connection which they want to use for their business network and SBS 2011 Server as well as allow for OWA and Smartphone access to Exchange. The new connection also has its own static IP.

Is there a way to configure 2 WAN connections on the SonicWALL, each with their own static IP? We like to keep the internet traffic separated between the two subnets but keep the local traffic between the two subnets open over the currently specified ports. Also, we need to keep in mind that ports like 80 and 443 are utilized by both the Webserver and OWA (Exchange), so traffic coming in from the original internet line (Static IP 1) over port 80 needs to go to the Webserver (Subnet 1), while traffic coming in from the new internet line (Static IP 2) over port 80 needs to go to the SBS/Exchange server (Subnet 2).

Does this question make sense, and if so, is it possible? If so to both, how I do this? Thanks so much in advance.
