I’ve got an isp which offers a service on a shared carrier – the isp is kind of misconfigured in that it will try to route packets via the ip address of my peplink wan interface to some random destination network (a destination ip other than the ip of my peplink wan …). There is an idea that my peplink is then receiving the packet, seeing that it doesn’t have any internal routes to such a network and then reforwarding it back out one of its available wans as determined by outbound policy. Is this possible?
Can I stop this with an inbound firewall rule?
Thanks,
Ben
