On the ipfire router. A quick google turns up commands like: ip route get <IP> and ip route list cache match <IP> and if a redirected route exists, it is labelled that way in the output of such commands.
If this is happening, it will be triggered by any traffic is forwarded to 10.96.25.1. Also, it shouldnt cause any problems. Other than a traceroute output not quite being what you expect, is there any problem? If everything's good dont worry about it (unless your curiosity is piqued).
