You can connect multiple routers on the same fiber optic cable using different subnets by configuring static routes or using firewalls/VLANs to manage traffic between them.Network ConfigurationWhen ro...
When routers share a single fiber connection but operate on different IP subnets, each router must have its own default gateway for its subnet. Devices connected to each router will use that router as their gateway, and communication between subnets requires routing rules or a Layer 3 device to forward traffic appropriately .
Connecting routers on the same fiber with different subnets is feasible by using static routing, VLANs, or multiple IPs on a single WAN port. Proper configuration of gateways, routes, and firewall rules ensures that each subnet operates independently while allowing controlled inter-subnet communication. Avoid overlapping subnets on the same physical network to prevent broadcast conflicts and latency spikes .
You say these routers support port-based VLANs, so I''d do it like this: Set up a port-based VLAN (untagged) on both
Learn how to connect two routers to one fiber modem for better WiFi coverage. Discover setup steps, potential issues, and network
But I would like to know, technically is it possible to connect new router directly to the fiber modem? (my fiber modem has extra RJ45
When set up correctly, you should find that all devices on your network automatically have an IP address that starts
This would break down if i chose in the same subnets different IP''s, they would not be able to ping each other with out
Both of my routers are using Openwrt and I am not too sure about how to configure a LAN port on both routers to be
My problem is that I have machines on the same subnet in both locations, but I dont want to traverse the trunk if my traffic stays
A former ISP, sonic , offered six static IP addresses with their monthly service. You don''t need a router. You just need a hub or
In case my other router is connected to the LAN port of the main, will the second router be on the 192.168.0.2 e.g. ? or
We have a 500m fiber connection and for years have only had one single IP. Recently I had a block of IPs added so
I tried different Switches and also reduced my network setup to 1 device + 2 Fritzboxes but I still always experience
Can anyone tell me what some of the implications of having two different subnets on the same switch would be if
A common confusion arises when devices are on different VLANs but share the same IP subnet: they can''t
The first two are reasons to have a separate broadcast domain for IP camera''s but not necessarily reasons not to have two subnets
You can use any two private IP address ranges as long as they are different. The top router (“Internet”) takes the single Internet
You cannot have the same IP network on different layer 3 interfaces of the same gateway device (router or layer 3
Do those routers have a third interface you can use to physically connect them (assuming they are in the same location
If you do, keep in mind that the router will need to do its job and "route" all the traffic between the different subnets. With a single
Could someone please explain why a router can''t have 2 interfaces on same subnet? Do routers use network
A fiber connection is really no different than just running an ethernet cable between the two buildings, at least not from
Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between
There is no need to get extra IP, it doesn''t really solve some potential issues. The easiest way to do is, terminate your ISP
You will then want to configure subinterfaces on your ethernet port on the router- each IP address on the ethernet

Hi, we have both iptv and internet from our isp and the iptv is on different subnet on dedicated ports on the
That is going to depend on the router. For example, a Ubiquiti USG has dual LAN ports, and
