Port forwarding basics

[Juggy]

Can someone please help me out? I’ve had 4 friends help me, who know much more than I do about PC related things (though I feel I do know a lot), and no one has been able to help out.

I’m trying to forward ports for MAME but I’ve had no luck. I’ve tried everything I can think of. Portforward.com doesn’t have my router and no one seems to know what to do. When I go to http://192.168.1.1 I can’t find anywhere to forward ports and can’t get anywhere.

I have:

SOHO-IS104A router

-_-

You shouldn’t have to forward anything to join servers. Only create them.

Lol…4 people couldnot help out. Anyways, you want to learn how to do it, the following is from your router’s man pages:

2-4-1 Special Application
Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and others. These applications cannot work when Network Address Translation (NAT) is enabled. When users send this type of request to your network via the Internet, the Router will forward those requests to the appropriate PC. If you need to run applications that require multiple connections, specify the port normally associated with an application in the “Trigger Port” field, select the protocol type as TCP or UDP, then enter the public ports associated with the trigger port to open them for inbound traffic.
? TCP (Transmission Control Protocol) - A method (protocol) used along with the Internet Protocol (Internet Protocol) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet.
? UDP (User Datagram Protocol) - A communications method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the TCP and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one computer to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn’t provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP.

Example:
ID Trigger Port Trigger Type Public Port Public Type Comment
1 28800 UDP 2300-2400, 47624 UDP MSN Game Zone
2 28800 UDP 2300-2400, 47624 TCP MSN Game Zone
3 6112 UDP 6112 UDP Battle.net

There is a nice coloured picture there as well but i am too lazy to copy it.

Actually, this doesnot make much sense. Port forwarding is rather related to the “virtual server” setting in your router configuration page.

Fixed it. There were two firewalls and only had one disabled.

Next problem: Only 3 servers are playable and none have more than one or two games. Rest are in Brasil and other countries with 150-500 ping.

What emu are you using? If you aren’t using mame32k 0.64, download it from www.anti3d.com. It has a current server list inlcuded, as well. Where are you from? If you’re in US, there are 5 or 6 playable servers right now, GodWeapon being the most popular. Also, you should not disable your firewalls, as that is a security risk. Simply figure out how to allow kaillera/MAME to access the interent through the firewall. If it’s a smart firewall, it should be as simple as going to some setting within its GUI, figuring out where to “allow” programs, then navigating to the executable for MAME.
