This video covers how to configure non-standard ports in SonicWall device. Manually opening non-standard (custom) Ports from Internet to a server behind the SonicWALL in SonicOS Enhanced involves following four steps:
Step 1: Creating the necessary Address Objects
Step 2: Creating a Custom Service for non-standard port (custom port number)
Step 3: Defining the appropriate NAT Policies (Inbound, Outbound and Loopback)
Step 4: Creating the necessary WAN to Zone Access Rules for public access
The example used in video covers allowing non-standard port from the Internet to a server on the LAN with private IP address. Once the configuration is complete, Internet users can access the server behind the SonicWALL UTM appliance through the WAN (Public) IP address.
If you have any question/doubts, please let me know and I'll get back to you asap.

There are situations when we want to save the state of our objects to the system, for example when our app has to go in the background, or to terminate.
Of course, we can do our way for saving our objects, but iOS SDK provides us an elegant way for doing that by using NSKeyedArchiver - to archive objects, and NSKeyedUnarchiver - to unarchive objects.
But in order for those methods to work correctly, we need to implement 2 instance methods in the class we want to be able to archive, or unarchive.
These methods are mandatary in such situations, and should look like this:
- (void)encodeWithCoder:(NSCoder *)coder
{
[coder encodeObject:somePropertyOrField forKey:@KeyName];
}
- (id)initWithCoder:(NSCoder *)coder
{
self.propertyName = [coder decodeObjectForKey:@KeyName1];
fieldName = [coder decodeObjectForKey:@KeyName2];
return self;
}
somePropertyOrField must be a property or a field of our class; @KeyName, @KeyName1 ..., @KeyNamen may be arbitrary names we choose.
To archive (save the object on the File System), we use:
[NSKeyedArchiver archiveRootObject:objectName toFile:@/Users/pavel/myObjectState.plist];
which create the .plist file (which a special XML-format file in iOS) at the indicated path.
To unarchive (restore an object state from a file), we use:
MyClass *newObjectName = [NSKeyedUnarchiver unarchiveObjectWithFile:@/Users/pavel/myObjectState.plist];
which initializes the new object with the corresponding values from the .plist file. Archiving and unarchiving objects in Objective-C](https://i.ytimg.com/vi/KSIU8zRi7zk/mqdefault.jpg)
