Assalam o Aleykum, this is my first thread here guys, and after searching much on the web and doing quite a bit of arguing with call centre representatives, I have felt the need to open a thread up here on pg forum.
First, I will tell you about this CGN thing, this is a technique used by isps when they want to go absolutely cheap.
So you guys would have noticed that when ever we restart our router/modem, our ip gets changed, that is because isps always try to go cheap and use dynamic ips instead of allocating a static ip..
Now, if you see your WAN ip address under the info tab of your router/modem device, it will display a certain ip address.. IF this address starts with 10.x or 192.x then you are in for a bumpy ride of cgn.
Now if you google 'whats my ip' you will see a certain address, IF that WAN ip address of your router is NOT same as which google displayed in search results, and it starts with 192.x or 10.x or any ip address that is used for assigning to internal ip (you can search on the web to see all ip addesses that are used as internal ips), then you have CGN enabled on your network.
Basically, when we use internet there are two things mainly involved, one is your local machine ip address (internal ip address, which is always 10.x or 192.x and its assigned by your router/modem device) and second is public ip address (external ip address also called WAN address, its assigned by your isp, and it should NOT be in the range of 192.x or 10.x unless your isp has deployed CGN). Now router/modem purpose is to mainly transfer data to and from the both addresses.
So, CGN purpose is mainly to cut costs and use a single public ip address for all users behind a cgn router which is deployed at isp level, hence a private ip address is assigned to a user's wan ip and only one public address is used for thousands of external wan ip addresses to connect them to internet. Imagine it like an extension cable, you can plug your tv directly in the wall socket, but you don't have any more spare sockets there and you need to connect your stereo speakers and pc and you want to go cheap instead of buying and fitting a new socket in the wall, then you will need to use an extension cable, connect all your devices with it and then plug it in the wall socket. Thats CGN.
Isn't that a good thing? Yes it is absolutely, but for the network provider and not for the consumer. CGN blocks all incoming ports permanently, while it does increase security and protect from attacks, but while doing so it causes huge issues for connecting and playing multiplayer games (specially which are based on p2p technology) and some applications like utorrent, while internet is still accessible for them but it causes much connection issues and lag, and due to ports permanently blocked at isp level one cannot do port forwarding either, even enabling dmz (demilitarised zone) won't work.
CGN causes increased pings and lags, sometimes degrades performance too, I was surprised how much connection issues I was facing when playing games (particularly GTA Online which is based on p2p) no matter which network I used, so after much research I got some insight on this, strangely every mobile network in Pakistan has CGN deployed (all 4 mobile networks which I tested), other than ptcl evo and ptcl broadband (which I didn't tested, although I know ptcl is offering static ip, so it shouldn't have CGN), so I would like users to test about this CGN on their routers/modems too by above mentioned procedure. And do tell me if someone is using a mobile network and there is no CGN for them or no connection issues/smooth experience of multiplayer, also do tell me about your network's performance in playing multiplayer games and your ping times and lags (if any). This CGN has become a big issue (for me atleast). Also a list of networks that deploy CGN (country wide or certain areas) would be extremely useful..
In the end, enjoy your gaming and lets hope the best for our country's advancement in technology !
