Need Help Configuring Sonicwall Firewall

[estone4009]

I have a Sonicwall XPRS2 that I need help configuring. We have a program that we run internally that is supposed to connect to a certain IP on the web and the sonicwall then forwards it internally to the correct machine. The problem is that this IP is the IP of the sonicwall. So everytime we try to start the program it stalls. Reason being is that the sonicwall see's this as a internal address. DUH. Well, how do I get it to pass it through even though it see the problem.

Thanks

I'm guessing you're NAT enabled here, but you need to set up a network access rule that declares the IP of the internal machine with the program as a "Public" server. You will probably also want to assign that machine a static IP adddress.

You can set the access rule up on the Access tab of the SonicWall admin page by using the Add Service, Service, and Rules pages. You will also need to know what IP ports the program is wanting to use for communications.

Yes, I'm using NAT. I have a a service set up that uses port 516. That is the port the program listens on. Then I have a rule that allows everyone (should be anyway; LAN, WAN, DMZ to access that internal IP. But I'm still missing something. Can you explain your setup in more detail?

Can anyone else help me out? I still can't figure out what I'm doing wrong.

Thanks,

Hi there,
I think I can help now that we have got our SonicWall working correctly..

Although you can set-up a rule within SonicWall to allow traffic through to a certain port, SonicWall has a "RULE 0" which seems to effectively block anything that trys to talk directly to the server or PC behind it.

This rule cannot be seen in the rules list, and also cannot be changed.

You need to get the external access clients or whatever you are allowing through, to point to the WAN IP of the Sonic Wall and then let SonicWall handle it to the server.

I did this with our ADSL Router/Modem after thinking I had everything right and should have worked, but then found out about this rule zero. Great rule,. but not much good if you don't know about it. SonicWall do not seem to publish this anywhere?

Hope this works and helps
