Reverse proxy server construction: private protocol encrypted transmission and internal system extranet mapping

Reverse Proxy Servers Playing in the Wild

We may have heard of the reverse proxy server this thing, but today we want to talk about something different - using proxy IP to engage in private protocol encrypted transmission, and incidentally, the internal system mapped to the outside world. Don't be intimidated by the terminology, in fact, this thing is similar to installing a security door at home, the core of the two things:Hide the door.,make the key specialThe

The weaknesses of traditional reverse proxies

Ordinary reverse proxy is like a transparent glass door, although it can block outsiders from entering the room, but outsiders can clearly see what furniture you have in the house. With ipipgo's dynamic residential IP base, equivalent to the glass door to paste a layer of one-way see-through film - the outside is an ordinary house, can not guess what is running inside the business system.

Here there is a pit to pay special attention to: do not use the cloud service provider's fixed IP, these IP segments have been marked by the crawler through. Previously, a customer with a large factory IP for mapping, three days every now and then by the malicious scanning, replaced with ipipgo's residential IP pool, scanning requests directly down eighty percent.

Cloak and dagger agreements

Common protocols such as HTTPS/TCP are like uniformed courier boys, walking on the street is too eye-catching. We can design our ownhybrid encryption protocolthat disguise serious data packets as everyday communications from home IoT devices.

Here are three benefits of recommending the socks5 protocol supported by ipipgo to hit the bottom:
1. Ability to customize authentication methods
2. Support for UDP/TCP dual-channel
3. Traffic characteristics are not as pronounced as those of specialized agents

When configuring, remember to disguise the heartbeat packet as a smart home timed report, such as this setup setting:

Blindfolds for extranet mapping

Directly mapping out the intranet port is equivalent to hanging a sign at the door, here to teach you two tricks:

1. Dynamic port hopping: Use ipipgo's API to change the exit port in real time, using a new port for each connection, just like changing a different door number every day!

2. IP drift: 90 million + IPs in the residential IP pool rotate, the same business that comes out of a US IP today may become a German IP tomorrow

The actual test of this program than the traditional program to enhance the covert 70%, a cross-border e-commerce friends rely on this trick, hard to disguise the business system as a home monitoring server, safe operation for two years have not been stared at.

Frequently Asked Questions QA

Q: Why should I use a residential IP instead of a server room IP?
A: The IP segment of the server room is like an office building, which is too conspicuous for a sudden server traffic. Residential IPs are "ordinary residents" in residential areas, and the traffic characteristics are more hidden.

Q: Will ipipgo's dynamic IP affect business stability?
A: Their long-lasting dynamic IPs can remain unchanged for 24 hours, enough to maintain a persistent connection. There are also static residential IPs available when a fixed IP is required, which has the same effect as home broadband.

Q: Would it be a hassle to get private agreements on my own?
A: Using off-the-shelf tools to change it saves time compared to developing it from scratch, for example, transforming the headers of the websocket protocol into a smart home protocol can be done in half an hour for the basic version

In the end, this security thing is a cat and mouse game. Using ipipgo's global residential IP resources as a base, along with a little bit of protocol modification tricks, is much more effective than simply piling up hardware firewalls. Next time you want to map the internal system, remember to put on a "plainclothes" for your business before you go out.
