Multiple Wan IP's one Router


  Hi,

 I have two WAN IP's from my ISP. I want this senario...

  IP1---|                                                     |--- NT Server 2003 (1) Traffic form IP1 come here
          |------[DSL]----[Wireless RouterA]----|
  IP2---|                                                     |---NT Server 2003 (2)  Traffic From IP2 comes here


                                [Motorola Wireless Hub] ----- NTServer 2003 (3)  Talks to Router A

   Is there a single Wireless router that can be configured for this setup? OR do I need two Routers
amd a Switch. I have a TRendNEt 431BRP which allows Multiple DMZ's to be assigned to different
WAN IP's is that the solution?

You need to look into the buisness  products offered by CISCO, general consumer products will not do it for you.

You can also lookinto a multi WAN WIFI router (a google search should come up with something for you)

Sorry I can't offer any spacifics,

No question an appropriate Cisco unit would be your best bet, but if looking for a less expensive solution there may be other options.
-Do you need to have the NT servers connected by wireless ? If not there are some very affordable dual WAN port router's such as the Linksys RV042, which will also offer some static routing capabilities if necessary.
-Though it may look a little clumsy, you could do it with multiple routers
-You mention you have the option of putting the servers on the "Multiple DMZ's". The DMZ of course is less secure, what are the servers used for? Can you afford the reduced security? If web servers or equivalent that would be fine.
-You want Server 3 to talk to Router A, are all servers to be on the same subnet, or isolated?

More questions than answers  <G>, sorry.

Thanks for the answers. I' looking for a solution around $250 and it has to be wireless there are a bunch of other PCS in the network.

 I dont need a dual WAN port. I need a single port. I have multiple static IP's..I want to route traffic from one IP to one server and from another IP to another server. Traffic to both IP's comes into my DSL box.
 
  If I set the IP of my router to one IP or the other I can ping both. So I'd like to give the router two IP's so to speak. Then route the IP's to specific servers.

  If I have two routers hanging off the DSL modem thru a switch can it be done that way?

Yes or with the 2 connections going to the dual port router. I have a couple of clients who set up 3 or 4 routers this way. Works fine but a single Cisco unit would be 'cleaner', but of course quite a bit more.
You could always set up the basic wired system and add a wireless access point for the wireless users.

Rob,

    I found a non wireless broadband router. I hooked the DSL to a hub then the two routers (1 wireless one non to the hub). I configured both routers with the external IP's. I then hooked the Two nt servers to the routers and port forwarded port 80.

 Bingo it works!

  I now have two Web servers running on seperate WAN Ip's.

  I still have the wireless router for the wireless in the family.

  Another problem I overcame was having the computers on one router talk to the other.
I put both routers on the same subnet 192.168.0.2 and 192.168.0.20 disabled dhcp on the .20.

 Now all the computers on the internal net can talk to each other. Time for a beer!

 Thanks for your help

Bill

Love it when a plan comes together !  :-)

One note about your configuration. Where you have put the different devices on the same subnet, which is fine, pay attention tho the "Default Gateway" assigned to your client's in their NIC's TCP/IP properties. Once in a while you can come up with a problem, especially with an incoming service trying to come in through one router and back out through the other (the default gateway). On occasion with services such as a VPN you might have to add a route command to force the service back out through the same router. I only point this out as someday it may come up.

Cheers,
