![]() first 3 numbers in address are the same) sender will obtain real MAC address (via ARP) of destination and send packet directly to that MAC address. If network mask is 255.255.255.0 (as it looks like from your example) - then for addresses in the same subnet (i.e. To perform this conversion sender checks whether destination IP is in the same subnet as its own address, this is where network mask comes into play. ![]() Next step is to forward received package to destination, switch uses destination MAC for that, if that address already in internal table - packet only forwarded to already known physical port, if not - to all physical ports (note: packet is forwarded as is via specialized hardware chip without modification, thus it is very fast).Īs you see - there is no any kind of IP address involved in this process, so, to make things actually work sender's host first converts destination IP address into MAC and then send package via wire to switch. When switch gets packet - it inspects it source MAC address and preserves this information in internal table, so it has association MAC physical port. ![]() Usually switches work on L2 level (lets omit 元 level "smart" switches, which are actually routers in common terminology). LAN2 - physical port where subnet is connected.LAN1 - physical port where subnet is connected.WAN - physical port where ISP modem is connected.yes, packets will go through firewall, thus limited to 1Gbs.no, packets will run directly between hosts at line speed 10Gbs.different segments and different IP ranges) do all the packets need to travel first through the firewall to get to it? In other words, despite being on same 10Gb/s switch does traffic travel at slower 1 Gb/s port speed of firewall? If copy a file from computer A to B (same LAN segment) do all the packets need to travel first through the firewall to get to it? In other words, despite being on same 10Gb/s switch does traffic travel at slower 1 Gb/s port speed of firewall? all computers are using the same switch but not the same IP range.Computers X is on LAN2 (on same physical switch but different IP range of ).Computers A and B is on LAN1 (on switch IP range ).The switch has been segmented into 2 different LANs (i.e.Each of the firewall's outbound ports physically connects to the same 24-port 10Gb/s switch.The firewall device has additional two 1Gb/s ethernet ports that each dole out separate IP ranges.ISP's Internet router/modem is connected to a 1Gb/s inbound port of a firewall device running Pfsense.You may want to have both modem and router in your network (modem will need to be launched in bridged mode). ![]() Note: modern voice system will require your network to have a router in it. Despite the fact that some modems have integrated router features, they barely capable of maintaining voice systems functionality. Having several devices with DHCP enabled will lead to a DHCP Race Condition - also known as Conflicting DHCP Servers. In case you have several devices on your network that support DHCP, you need to make sure that only one of them is configured with DHCP.
