Forwarding tab
This section is to open up your internal network to the outside - the Internet. Under 'Ext.Port', the first box is from this range
(including this port number), and the second box is ending at this range (including this port number). So when I forward only one
range, you'll only see 27050 To 27060, which means port 27050 through 27060 are only open in the above picture. From the picture
above, you can see that I have opened four port ranges allocated to four separate computers (192.168.1.50, 192.168.1.100,
192.168.101 and 192.168.1.102) to the outside world (ten ports for each computer/laptop to use). I've done this to allow each
computer/laptop to have at least ten ports available at their own disposal to do whatever they need, whether they wanted to create a
server, host game servers, etc... Each computer gets ten port to use for such things. More can be assigned, but I only did this for
an example. These port numbers can be something else other than the above, etc... Just go
here to read which ports are usually
used for. Also, on that page, it has another link to RCF 1700, which lists ports that are assigned. You should be able to use any
ports between 1024 - 65535, as long as it doesn't conflict with any other programs that use such ports that you wanted to use and
forward.
Some IRC networks require Ident to let you onto their server like DALnet and EFnet, to name a couple. If a computer or multiple
computers want to use mIRC and connect to a server that requires Ident, you need to use Port Triggering, a button below the port
forwarding boxes. Click the Port Triggering button and you'll something this:
mIRC
In order to get Ident to work, you need to input the following:
Application Name: mIRC-IDENT
Trigger Port Range: 6660 ~ 7002
Incoming Port Range: 113 ~113
After entering all those information, click Apply and close out of the window by clicking the X box on the top right hand corner.
All that information should look like in the above screenshot.
Doing this should allow multiple computers to get on IRC servers that requires Ident. You'll have to wait for a couple of minutes
in between each Ident usage for each computer. Also make sure that you have the option 'Enable only when connecting' checked under
mIRC's Files-> Options-> Connect-> Identd.
Now, if you want to be able to DCC-Send (DCC-Receive shouldn't be a problem), you must do the following:
1. Launch mIRC.
2. Go to File -> Options.
3. Go down to DCC, click it to expand it.
4. Select Options under DCC's expanded list.
5. Change the DCC Ports according to the port(s) you forwarded to that specific computer. Default is First: 1024 and Last: 5000.
For an example, in the below picture, I changed it to 27050 for first and last to 27060, for computer that has 192.168.1.50 IP
address (look at what ports you forwarded in the Forwarding tab section and to which computers). I also changed the Max. remote
requested DCC Sends to 10, because 10 ports are opened to accept only 10 connections through. Increase the max requests by forwarding
more than 10 ports like I did for this guide's example. Make sure you also change the DCC ports' first and last ports as well if you
change the range. After doing this, DCC Send should work.
This is why it is ideal to have static IP addresses. It's much easier to know which ports are forwarded to which computers. It
also stop DHCP from randomizing your LAN computers' IP addresses and thus makes you change which ports are needed to be forwarded to
which computers every time. This way, for instance, computer #1 will always have port 27050 through 27060 opened (Protocol Both - TCP
& UDP), and that computer user will always know that when hosting a game server, a FTP server, or whatever program that needs to
have an open port, the user can just use port 27050 through 27060 whether the program uses the protocol TCP and/or UDP. Remember that
you can allocate more open ports for a computer. Just remember that you cannot overlap any ports and you can't forward the same port
to more than one computer. Of course, how DHCP is used for the mobile computer, the IP address won't be other than 192.168.1.50, since
only 1 DHCP user was allocated within the router's option back in DHCP section. This means that you can forward the port and have
the mobile user always know the open port - 27050 through 27060.
