IPWhiteList
Limiting Clients to Specific IPs {: .subtitle }
IPWhitelist accepts / refuses requests based on the client IP.

Configuration Options
sourceRange
The sourceRange
option sets the allowed IPs (or ranges of allowed IPs by using CIDR notation).
ipStrategy
The ipStrategy
option defines two parameters that set how Traefik determines the client IP: depth
, and excludedIPs
.
ipStrategy.depth
The depth
option tells Traefik to use the X-Forwarded-For
header and take the IP located at the depth
position (starting from the right).
- If
depth
is greater than the total number of IPs inX-Forwarded-For
, then the client IP will be empty. depth
is ignored if its value is less than or equal to 0.
!!! example "Examples of Depth & X-Forwarded-For"
If `depth` is set to 2, and the request `X-Forwarded-For` header is `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` then the "real" client IP is `"10.0.0.1"` (at depth 4) but the IP used for the whitelisting is `"12.0.0.1"` (`depth=2`).
| `X-Forwarded-For` | `depth` | clientIP |
|-----------------------------------------|---------|--------------|
| `"10.0.0.1,11.0.0.1,12.0.0.1,13.0.0.1"` | `1` | `"13.0.0.1"` |
