Proxy IP and Firewall Configuration_Security Policy to Prevent Unauthorized Access

The real-world value of proxy IPs in firewall security policies

In enterprise network protection, a firewall is like a building's security system, while a proxy IP is the equivalent of issuing a dynamic ID card to each visitor. When the two are used in combination, they can effectively solve the traditional firewallbroad-brush interceptionThe problem of business interruption is brought about while improving the accuracy of access control.

Why Proxy IPs are the Gold Partner of Firewalls?

Traditional firewalls often encounter three pain points when controlling access through IP black and white lists:

1. Fixed IPs lurking for a long time after being maliciously cracked
2. Frequent adjustments of access rights are required by business units
3. Difficulty in maintaining IP address repositories due to multiple locations

Technicians can set up firewall rules to allow only specific business systems to be accessed via dynamic proxy IPs, and even if an IP is acquired by an attacker, it will automatically expire at the next update cycle.

Four steps to build an intelligent protection system

Step 1: Create an access identity group
Create separate IP pools in the ipipgo console, by department or business type:
- Financial Systems Group: fixed allocation of 5 exclusive IP segments
- Crawling Operations Group: Enabling Dynamic Rotation Mode
- Temporary visitor groups: set up temporary tunnels with a 1-hour validity period

Step 2: Configure firewall association policies
In the firewall management interface:
1. New "Proxy access" rule group
2. Import the IP address certificate provided by ipipgo.
3. Set protocol whitelisting (e.g., open only HTTPS port 443)

Step 3: Setting up a fusing mechanism for abnormal traffic
When the frequency of single IP accesses exceeds the threshold:
1. Automatically send replacement requests to the ipipgo API
2. Synchronized firewall rule base updates
3. Triggering the secondary authentication process

Step 4: Establishment of an audit trail
Through ipipgo's traffic logging feature:
- Associate the actual user of each IP
- Record a full session timeline
- Automatic report generation for abnormal operations

Enterprise Protection Frequently Asked Questions

Q: Does frequent IP replacement affect business continuity?
A: ipipgo's smart routing technology enablessensorless switchingThe IP replacement is accomplished without interrupting the TCP session, and the business system has zero perception in the actual test.

Q: How to prevent proxy IP from being impersonated?
A: It is recommended to turn on ipipgo'stwo-factor authenticationThe function binds IP authorization to employee accounts and device fingerprints, so that they cannot be used directly even if the IP is leaked.

Q: How do I ensure speed when accessing across borders?
A: With ipipgo's intelligent route preference system, you can automatically select theLowest physical latencynodes. We have dedicated backbone access points in Frankfurt, Singapore and São Paulo.

Core skills for precision protection

Recommended for ipipgoProtocol Level FilteringFunction:
- Blocking Proxy Requests on Non-Used Ports
- Restrict explicit protocols such as FTP to intranet IPs only.
- Enable temporary tunneling for management ports such as SSH

Enterprise administrators can incorporate ipipgo's real-time monitoring dashboard to createThree-dimensional protection view::
1. Geo-fencing: restricting IP access to specific areas
2. Time policy: Enabling enhanced authentication during non-working hours
3. Behavioral characteristics: identifying unusual operating patterns

This dynamic protection system can shorten the response time of unauthorized access attempts from hourly to secondly compared to traditional solutions. After the access of an e-commerce platform, the illegal scanning volume of its servers dropped by 83%, while normal business traffic was not affected at all.
