SERIOUS SECURITY LAPSE IN EXTREME SUMMIT SWITCHES. We have a Summit X450e-48p switch, in which we have created a Vlan that is acting as a gateway for the hosts. The switch is configured to forward the traffic to the router (internet). However this has caused a serious security issue which is as follows. A host has entered the IP address of the gateway and is getting all the traffic routed through his host machine to the router. Is there any way to stop such a situation, I think its called gateway spoofing. note: The IPs are being assigned manually to the host machines (no dhcp). Please help!!!!!!
1.)also note there is no way to make a policy (egress) to stop this.
2.)there no way to bind ip address to a port.
