Product: Belkin F5D5230-4 4-Port Cable/DSL Gateway Router
Firmware 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.
This continues until the router is reset.
The incorrect IP address is logged in both the server's log and personal
firewall log.
Notified Belkin 09/May/2002, no workaround or fix received yet.
