Re: Subnetting issue? Can only access 8 out of 16 addresses I asume you setup ARP on all addresses? Try removing them and adding one at the time only. Add a test PC to the interface in question (with the IP in the subnet, eg the one from the router in front). Start a tcpdump on the firewall on the WAN interface and ping all IP's from the laptop for which the firewall should respond (eg has a proxy ARP). Check if the firewall sees any ARP request and response to them. |
