- Topology: modem with router and Ethernet LAN bridge <---> server having one NIC.
- Server network interface: It is capable of handling more than one IPv4 address. All addresses are within the same subnetwork.
- Modem: Does the routing service and nothing else. Itself has one address for both WAN and LAN, also within the subnetwork.
Will there be an address conflict or will the ARP table have more than one IP, but always the same MAC address? We did encounter packet loss or host unreachability. The modem's ARP table did contain all addresses apart from its own, all associated with the same MAC.
