Multiple WAN interfaces on SonicWall TZ 100?

Question

Right now we can print out one line from out from a textfile by pressing the line number. Problem is when we are able to print out a line number again (products), until we reach the limit of products in our textfile. How can we stop the loop so it only print the one line we choose?

static ArrayList<Product> printOneLine() {
    ArrayList<Product> oneLineList = new ArrayList<Product>();
    Scanner oneLine = readDetails("Products-JavaBikes.txt");

    while (oneLine.hasNextLine()) {
        oneLineList.add(getProduct(oneLine.nextLine()));

        Scanner input = new Scanner (System.in);            
        System.out.print("Please enter a number:");

        for (int i = input.nextInt(); i < oneLineList.size();) {                    
            System.out.println(oneLineList.get(i));
            break;
        }   
    }
    return oneLineList;
}

Solution

On the Network>Interfaces page, click on the "Show Portshield Interfaces" button on the top right of the Interface table. That will show you the other interfaces.

Then edit X2, change it to the WAN zone and set the IP assignment to DHCP.

The S****wall TZ100 series definitely does support multiple WAN interfaces.

I think I initially misread your response. So it DOES support multiple WANs? That's good news. I thought so. I'm sure there's an easy solution. I have a parallel post at SonicWall. Will let you know if I get an answer there.

Are you running the "Enhanced" version of SonicOS? You cannot change an interface's zone from LAN to WAN in the "Standard" version.

I am running SonicOS Enhanced 5.6.0.11-61o. I was able to get the X4 interface shifted over to the WAN zone. I was also able tell it to use DHCP. It doesn't want to pick up an address though. Log says, "Retransmitting DHCP DISCOVER"... but no response from DHCP server.

Is there a reason why you ask the number inside the line iteration loop instead of asking it just once in the beginning and then using the result for finding the correct line?

[Stimpson Cat]

You should get the number from the user interface and then you can just return oneList.get(userEnteredLineNumber);

[Bernhard Barker]

That for-loop makes no sense, I imagine you're looking for an if-statement instead. For loops are for looping, if you break unconditionally in the first iteration, you're doing something very wrong. Also, you may want to debug your code or even just think through what it's doing, step by step - it doesn't help you in the long term for us to just tell you how to fix your code.

#1 and #2 have already been done. My question was about how to do #3. Your snide comment is unappreciated. Did it ever occur to you that ISPs offer multiple DHCP addresses to customers for a reason? It's a very popular add-on service. Having multiple DHCP addresses is very common for home users who want to expose multiple services that both must use the same port (e.g. 443) and don't want the added expense of a static IP. You really need to relax.

Thanks for the reference. The documentation you linked to says that transparent mode is for "spanning a single IP subnet across two or more interfaces." But is this what I want? I'd be dealing with multiple IP subnets, no? They might give me an IP of 55.55.55.55 for one interface and 66.66.66.66 on another.

Yes, you're right, L2 bridging would be more applicable of the two choices.
