Product: Belkin F5D5230-4 4-Port Cable/DSL Gateway Router

Firmware version: Runtime code version V1.20.000

Hardware version: R01

Problem : Reporting incorrect IP address when allowing port 80 into internal network.

Description:

The Belkin 4-port Cable/DSL Gateway Router will forward a http request to the correctly configured http server in the internal network.

The reported IP address is correct, until a request from the internal network is tried.

From this moment the requesting IP address is always reported as the router's external IP address.

NIS and Xitami both report the request as coming from the router, instead of coming from the internet.

This continues until the router is reset.

Notified Belkin 09/May/2002, no workaround or fix received yet.
