Create your own TCP Proxy! [Hotel Safety 1]

[Thewicard]

Want to minimize your risk when running a hotel? Well I'm going to show how you can run a server ON-Shore without ever have to worry about Sulake taking it down.

What are you going to need?
A second windows server including the server you have. About any cheap OFF-Shore server will do.

Step 1:
Download Portmapper on the server which you want to use as proxy
And run through the setup!

Step 2:
Now, run portmapper, then it will appear in the system tray. The M you see



1) Right click the system tray icon of portmapper and click "Configure"
2) Now click the "Configure mapping" button and then click "Add"
3) Fill in your information. (port you want to forward and the ip you want to forward to)
Remember - portforwarding is needed in both servers!



Now click OK->OK->OK
And you're done - all connections done to that port will be forwarded.

Security tip: Use an anonymous vps to host this proxy, or pay for the vps that you use with prepaid VISA. Use VPN both when you administrate and when you buy the VPS.

To get your clients ip: Do the exact same as you would through cloudflare.
$_SERVER['REMOTE_ADDR'] = isset($_SERVER["HTTP_CF_CONNECTING_IP"]) ? $_SERVER["HTTP_CF_CONNECTING_IP"] : $_SERVER["REMOTE_ADDR"];

You seriously need a Windows server just to host a proxy on? Yeah, right.

nice sig btw
sure isn't advertising

It is indeed possible on linuxservers, but I belive most people here use windowsservers.
Reson you want to use an own server for proxying is Security, no need for this if you have 5-20 active users.

So you think it will be better security running your own TCP proxy on a Windows server when you have no excperience? don't think so.

You can also use a much better solution with lot's of features and you don't need a Windows licence.

Nice guide, I own a domain but it's running on a XAMMP for Linux server.
I'll see if I can find a way around for Linux.

Good guide though, thanks.

lol. Ugh. The stupidity.. arghh... Why buy a $30 windows VPS when you can buy a $5 Linux one.. Habbo community sigh.

This will work on most if not all distros. Tested on CentOS 5/6 and used for many projects:

cat /proc/sys/net/ipv4/conf/eth0/forwarding

sysctl net.ipv4.conf.eth0.forwarding=1

echo 1 > /proc/sys/net/ipv4/ip_forward

iptables -t nat -A POSTROUTING -s 99.99.99.99/24 -o eth0 -j MASQUERADE #Your proxy IP, provided by the VPS provider of which you wish to proxy from
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 1234 -j DNAT --to 88.88.88.88:1234 #dport = listening port #DNAT = Your REAL IP:Port 

Example usage:

iptables -t nat -A POSTROUTING -s 12.34.56.78/24 -o eth0 -j MASQUERADE 

Replace 12.34.56.78 with the IP of your proxy VPS.

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 1234 -j DNAT --to 88.88.88.88:1234 

change dPort 1234 with the port you want your VPS to sit on.

Change the DNAT 88.88.88.88:1234 to your IP:Port that your REAL emulator uses.

When done go to your client and enter your proxy VPS IP and the dport you entered.
