If the online video game you want to play doesn't use their servers through SCEA game servers, you will need to look up that game's TCP and UDP ports so you can connect to their servers. These numbers will allow your Sony PlayStation 3 to connect to the PlayStation Network and most of the online video games that use their game servers through SCEA game servers. TCP and UDP ports for the PlayStation Network and SCEA (Sony Computer Entertainment America) Game Servers

Simply follow the instructions in the great VisiHow how-to article above, to learn how to enter these numbers: Sony has many port numbers that you will need to open, and they are listed below. This firewall is very likely blocking your Sony PlayStation 3 from connecting to Sony's video game servers or networks, so the customer service representative you spoke to who told you that you need to open UDP and TCP ports is correct. Your wireless router includes a built-in firewall to prevent any unauthorized services, applications, or devices from using your internet connection. The customer service representative said I needed to get a UDP and TCP port open. I'm trying to get my Sony PlayStation 3 to work. If you begin noticing anything suspicious, introduce additional security mechanisms like IP tables or port knocking.I am trying to open a TCP port and UDP port for my Netgear router? Get used to going through your system logs. If possible, try to run ssh daemon only when you know you will be accessing the machine in near future an turn it off afterwards Introduce a mechanism of disallowing numerous SSH login attempts (with icreasing time-to-wait for subsequent attempts - I don't remember how exactly this is called - I had it enabled some time ago on FreeBSD and I recall it was quite easy - try searching some FreeBSD forums etc. If you really need such access, you should at leastĪssure that you have strong passwords for all the user accounts,ĭisallow root access over SSH (you can always log in as normal user and su or sudo then),Ĭhange the default port on which your SSH server would run, This is not only a risk of potential break-in, but also of network slow-downs while the machine is being bruteforced. They typically "knock" on the default SSH port of as many IPs as they can and once they find an SSH daemon running somewhere, the try to gain bruteforce access to the machine. There are thousands of bots set up by crackers that search the Internet for machines with open SSH port. Simply allowing ssh access to your machine from the Internet is a bad idea. 2) or any other machine with Internet connection. Many routers come with configuration options to easily contact with those.ġ) This is, again, a simplification - the actual device that is seen to the Internet is the modem - which can often be integrated with the router, but might also be a separate box.

There are quite a few free dynamic DNS providers. This would make your router periodically send information to a special DNS server that will keep track of your IP and provide you with a domain name. To solve this in an easy way, you can use a service called dynamic DNS. Otherwise, C will not know what IP it has to connect to in order to get to your router (and further, to A). If you do not have an Internet connection with a static IP, then you'd have to somehow learn what IP is currently assigned to your router by the ISP. So a bit more precise representation of the above example would be. Such connections through the Internet occur based on IP addresses. Here's an example for port 22 forwarded to machine A. You configure that by instructing the router that all the connections coming on a given port from the Internet should go to a certain machine on LAN. This is done based on port numbers - that is why it is called port forwarding. This consists in telling the router what connection from C 2) should go to which machine on the LAN. Port forwarding is what allows the third schema to take place. (That is, the router protects the machines on your LAN from being accessed from the Internet.) Notice that the router is the only part of your LAN that is seen from the Internet 1). -.-.Īnd the following is not allowed by default.
So if the A (or any other machine on LAN) wants to access the Internet, it will be allowed (again, just talking about basic understanding and configuration). Notice how your router normally works: it allows connections from machines on your LAN to the Internet (simply speaking). You have: A - your FreeBSD box, B - your router and C - some machine with Internet access.
