Intranet IP Address Proxy: Intranet IP Proxy Penetration Solution

What the hell is this intranet proxy thing for?

Many engaged in the operation and maintenance of the old iron have encountered this situation: the company intranet hiding dozens of devices, want to manage from the outside as if breaking into a maze. At this time if you find a reliableproxy IPWhen the springboard, as with the labyrinth installed a signpost. For example, the branch wants to check the headquarters of the monitoring system, directly connected to the fire will be shot dead, set a proxy IP will be able to bypass the restrictions.

Here's what to focus onipipgoThe unique skill: their proxy IP pool is deep and bottomless, and the survival time of each IP can be accurately switched to the second level. The last time I deployed an intranet penetration for a customer, it took five minutes to connect with their API, faster than cooking instant noodles.

Three tricks to fix the intranet proxy configuration

first move"reverse proxy" technique (computing)Take Nginx as an example, remember to bind the local port and proxy IP when you change the configuration file. Here's the kicker.ipipgoThe IP comes with authentication, so you don't have to toss password authentication.

server {
    listen 8080;
    location / {
        proxy_pass http://ipipgo-proxy-server:5000; proxy_set_header
        proxy_set_header Host $host.
    }
}

second moveport mapping tool: The netsh command that comes with Windows is actually a treasure. Knocking these lines in cmd immediately maps the intranet port 3389 to a proxy IP:

netsh interface portproxy add v4tov4 listenport=3390 connectport=3389 connectaddress=ipipgo-proxy-ip

The third move.SDK Direct Connect Solution::ipipgoOff-the-shelf Python packages are provided, and tunnels can be created in two lines of code:

import ipipgo
tunnel = ipipgo.create_tunnel(local_port=8000, proxy_type='socks5')

Record of actual pitfalls

Last year for the logistics company to do warehousing system docking, encountered a strange problem: proxy IP is always dropped. Later, I realized that their fire prevention strategy was too harsh, and they pinched the connection every 5 minutes. Replace it withipipgo(used form a nominal expression)Dedicated channel for long connectionsOnly then is it resolved that this channel can maintain a TCP connection for more than 12 hours without interruption.

A must-see QA session for the little guy

Q: Does proxy IP affect internet speed?
A: It's like driving on a highway or a country road.ipipgoThe measured latency of the BGP line can be pressed to less than 50ms, which is faster than many direct connections.

Q: How do I manage multiple intranets at the same time?
A: Inipipgo consoleJust build multiple tunnel instances and remember to label each one. Last time I saw a buddy who was managing 8 server rooms at once, all thanks to their multi-account switching feature.

Q: What should I do if I encounter protocol incompatibility?
A: Don't panic, their family supportsseven layer protocol conversionThe last time I used their HTTP to FTP gateway to interface with an old FTP system. The last time I interfaced with an old FTP system, I used their HTTP to FTP gateway to get it done, and the configuration file looked like this:

{
  "protocol": "ftp",
  "proxy": "ipipgo-gateway:2121",
  "auth": "auto"
}

Look for these doors when choosing a service provider

One final note to newbies, don't just look at the cheap prices. Likeipipgosuch mattersDedicated server roomThe only reliable, many second-hand dealers on the market IP is shared by hundreds of people. The last test compared, the same buy 100 IP, small workshop of 23 have been, and theipipgoThe survival rate can reach more than 98%.

Focus on three indicators: IP purity, API response speed, after-sales technical support. Some merchants blowing sky-high, really want to debug when even a document can not be found.ipipgoThe documentation station even has more than two dozen screenshots of troubleshooting error reports, which is the real deal.
