Real IP implement on Web application, which solve the problem that the server receiving requests through trust proxies or load-balancers without Transparent-Mode.
DEMONSTRATION
If the client IP is 203.169.1.37
, there are some connection situation for demonstrating referring by above sample code:
Load-Balancer normal network
your server is behind a Load-Balencer and in a private network.
Client | Load-Balancer | Server |
---|---|---|
203.169.1.37 → | 172.217.2.88 ↓ | |
192.168.0.10 → | 192.168.4.100 |
Setting proxyIPs
as true
means all requests are go through Load-balancer, which will always get forward IP, same as above setting:
The result from the server:
Proxy optional network
If your server is in public network, not only receives requests directly, but also supports trust proxies for going through:
Client | Proxy | Server | |
---|---|---|---|
Way 1 | 203.169.1.37 → | 172.217.4.100 | |
Way 2 | 203.169.1.37 → | 172.217.2.89 ↓ | |
