Network Question for Devs

Are you creating the Loopback Pseudo-Interface that gets created when the game executable are ran? Or is it something that is native to the client?

This loopback interface points to 5.79.111.36 which is now the retail forums and why you cannot connect to the retail forms when GamezBD is running.

 

Was wondering why I cant go on retail forums. Thought maybe kakao banned me .

 

I added in- and outbound firewall rules for the official Forum IP. See first post in here for IP. Worked for me.

 

In a way they may have. They may have purposefully change the forum IP knowing the reality of the situation. Or perhaps it was just coincidental. Either way does not appear that Kakao otherwise did something that banned the individual specifically. When you shutdown the client, I know sacrilege, the loopback adapter gets deleted and your routing returns to normal.

By doing so you may have bypassed the reasons why it is there in the first place and opened yourself up to problems in the future. My guess is that the loopback adapter has always been there but only recently manifested this behavior when the retail forums IP address was changed. And it was changed about 7 days ago from .5 to the current .6.

And my guess is that the loopback adapter is there to prevent your GamezBD client from talking to a hard-coded service for the retail system. So by modifying your system to bypass that it could be problematic. If everything is correct on your PC then when you close the game you can connect to the retail forums. When Kakao change the forum IP they may, or may not, have change the IP of the server that this is intended to block. If retail did so then when Gamez updates the client to match that version you would be able to access the forums again. If they did not then your client may be attempting to talk to retail.

Besides preventing your system from accessing the retail forums there is nothing bad/malicious about this loopback adapter. It is just sending connection request to 5.79.111.36 to a black hole. However confirmation from the Devs would be nice.

 

allowing the forum ip through doesnt cause any issues at all lol. Why would it. This reminds me when another pservers launcher put all kinda blocks on your system to block gamez. This stuff is salty people fucking with your system due to business reasons. bypassing that shit with an easy firewall rule doesnt cause any problems at all.

As of now this method isnt working anymore btw.

 

@xMovingTarget Attempting to bypass this functionality would not only allow you to connect to the retail forum but any other service listening at that IP. A lack of understanding of that fact leads to incorrect assumptions and can lead to problems. Not just with this situation but with all computer/internet related situations. Which is the primary reason internet security is such a problem, people don't know what they are doing they just want the result.

When a guild-mate of yours told me that you were playing with the firewall in order access the forums I was not sure how that worked, or that it worked at all. I am now positive that it never did provide a resolution to the issue.

However, the point of this post is to attempt to inform people, and hopefully get confirmation from the devs, as to why as of ~7 days ago we cannot access the retail forums when the game is running. And to also help educate as to why it would be a bad idea to try and bypass it.

Implementing a new loopback adapter is not "fucking with you system" as you so quaintly put it. It is a standard and accepted method of network programming. It is used to solve certain problems that arise due to differing system configurations, guarantee lower latency communication across the IP stack and for security to block access to certain IPs.

In this case it was probably, purposefully implemented to block your client from accessing that retail IP. You really want your GamezBD client to access retail? Specifically that IP was, perhaps still is, the auth IP for retail. You really want your GamezBD client to try and auth against retail?

Again, the overall point here is that yes you can no longer access the retail forums while the GamezBD client is running. Retail change the IP address of their forums ~7 days ago. That IP address they changed the forums to is/was the logon server for retail. The Devs here, most probably, implemented a loopback adapter with that IP on your system a long, long time ago to prevent the client from being able to talk to that IP. That loopback adapter implementation is a clean and secure way of making sure that retail IP is not reachable. Do not attempt to bypass it. When the GamezBD client is closed that adapter is removed and you can access the services on that IP address.

If all of my estimates here are correct I salute the Devs in implementing such a simple and clean method of security the GamezBD client. However, I would like the Devs to confirm or deny this.
