SonicWall NSA2400 port 80 options

Hi, we have a Sonicwall NSA 2400 and I'm trying to see if it is possible to have multiple websites point to the SW's public IP and have the SW route that traffic to a single internal webserver where it will be routed to the correct site. Currently we are using a redirect at domain registrar and then rules on the SW to redirect that port's traffic to the internal webserver. So on the DR we have test.site.com set to the SW public address and then at the DR there is a port 80 redirect for any port number, lets say 8888. The SW receives that info and forwards 8888 traffic to port 80 on the internal webserver. This has been just fine for us up to this point, but now we have a site that uses maps for field folks to find things. It appears that once into the site via the redirect, the site tries to access other internal pages on that site with the 8888 port number vice the default 80 and things don't work. If we could find a way to send multiple websites e.g. test.site.com, test1.site.com etc to the same public IP using no redirect and have the SW relay the traffic to the internal webserver and there it would be routed to the proper site. I know this is possible with an IIS server with a public address by using host header entries in the bindings. I just chatted with SW tech on it and he said it couldn't be done, but I'm not so sure since an external IIS server can do it, I would think an appliance like the 2400 could. Thanks for your ideas.

When you say "have the SW route that traffic to a single internal webserver where it will be routed to the correct site", do you mean that the internal webserver hosts all of the websites or are the websites hosted on various other internal webservers?

The majority of the sites are on one internal webserver; however, the site with the problem is a seperate server and it runs Apache (handled by a third party so I'm not privy to the ins and outs of it). I'm hoping that there is a way for the sonicwall to basically do what a webserver does and take traffic intended for site1.test.com and direct it to 192.1.1.1. and site2.test.com and direct it to 192.1.1.2

Unfortunately the Sonicwall cannot direct traffic between your internal webservers when you only have a single public IP.

You will need to setup a reverse proxy behind the Sonicwall and use that to direct traffic between your internal webservers as required. Then simply get the Sonicwall to route all HTTP requests from your public IP to your reverse proxy.

It would be a lot easier to ask your ISP for an additional public IP and use that though.
