TOPIC: 1 ISP TO 2 DIFFERENT ROUTER POSSIBLE CONNECTION

saken bawal yan

bawal online game na may fb o ibang game

Wont' work due to the following:
1. Without implementing VLAN and having uplink between 2 switches, that essentially put the all machines on the same L2 collision domain / ARP broadcast domain. In itself is not that bad, what makes it unacceptable is due to the below:
2. Ok, let's say na backup na yung isang router, eg ROUTER1-LAN1-192.168.1.2/24. That would require changes to DHCP and announce its leases as such. Or, gaya ng sabi ni Uber, by using netsh.exe to modify the routing table of each Windows machine. That is not an scalable and error-prone solution to a simple problem because you have to do that to each and every machines.
3. Most importantly, yung IP address ng modem is 192168.1.1/24. Ano ngayun ang IP addresses ng WAN Interfaces ng Router 1 and 2? 192.168.1.4 & 192.168.1.5?
3a. You can't have 2 or more IP addresses on the same subnet (eg 192.168.1.0/24) on the same device.
3b. The WAN subnet of the Routers must be different from their LAN's.

In short, Tomato, pfSense nor Mikrotik can make this work. This is a spaghetti design. Broken design is broken.

My two cents...why reinvent the wheel? something and anything can go wrong at anytime in a network system thereby rules were made, systems were put in place conforming to these rules so that in the future that you WILL and you will have to go through network troubleshooting, you will follow the troubleshooting guide that these network gurus had created and put in place for us that are not as adequately learned in this field to better comprehend. Rules are made, some are meant to be broken, networking is not one of them. That is how it works. Now if someone still insist and go on their own way, by all means do so, no one is stopping you to jump off the cliff. But, if you are just starting to learn the complexity of networking, I suggest you follow the rules first (baby steps). Learn to walk before before you run

meron na yata parehong topic nito donn sa tp link. di lang ako sure
at ganito ang mangyari sa set up ko kung down ang isang isp ko.
bali sa main router ni tplink mo lang hahatin ang papasok na bandwidth galing sa isang isp..
sample kung may 3 rotuer ka at isa lang isp mo
isp 100mpbs
router 1 50mb lang gagmitin mo
router 2 30mb lang
router 3 20mb lang
sa upload pwede ikaw ang bahala kung ilan ang ilagay mo.

yan ba gusto mo ts?
correct lang po ninyo ako kung may mali mga boss.

mukhang nayari ka nanaman (ngayon kay simpson)sa pinag popost mo.. wag ka ng lang sumali sa mga ganyang teknikal.. mahirap makisabay kung pang mayor lang ang level mo.. eheheh

3 routers for an internet cafe? I can imagine that your router-to-PC ratio must be extremely really high. And if you are implementing router failover or high-availability, that would require an enterprise class of L3 protocols such as VRRP, HSRP or CARP (pfSense, BSDs) in addition to a switch that supports those protocols. I can see that that is gonna end up a terribly complex infrastructure. The idea behind is that the protocol provides a Virtual MAC/IP address representing that group of routers. That group knows who is the master router and who is going to take charge if the master goes down. Then the DHCP server will announce their virtual IP as the default gateway.

Pinaka-simple, kung sakali pumalya yung router, unplug-and-replace yung hot standby router.

Oi, di ko kilala si boltron, sorry.

lolz out na ako sa thread, na ito pang lupon lang ang level ko. hahaha

But what do you think will happen if i plug the rj45 cable to lan1 of router1 instead of the wan port from ISP modem same thing to router2. With both routers set into router mode and every device in this network is on static IP and with the ISP modem doing all the NAT. All of them in the same subnet but with different IPs with all devices in this environment set to ISP modem's IP address as their gateway? :))
