Same segment IPs on different LAN ports.

RouterOS Beginner Basics
1

Hi, I have an hEX mikrotik routerboard and I need this configuration:

Eth2: WAN
Eth3: LAN 192.168.17.10
Eth4: LAN 192.168.17.20
Eth5: LAN 192.168.17.30

I connect eth 3-5 to a switch and then this switch is connected to another one, which is connected to the hosts.
I wanna be able to use all 3 IPs (.10, .20 and .30) as gateways, I already did it with a simple configuration and only one NAT rule to masquerade all trafic trough wan (eth2) but navigation isn’t the best, sometimes connection is lost.
I don’t want that a host with gateway .10 can communicate to .20 gateway, when I make a traceroute, all traffic goes to 192.168.17.10, which shouldn’t be that way, and communication between hosts to ther other gateways is successfull too.
The reason to use 3 LAN gateways is because 1 link isn’t enough to use all the bandwith we have, so, that’s why we have 3 links and wanna be able to have them in the same segment.

Tell whoever taught you these things that they’d better change jobs…

I guess you just don’t understand the idea of what a LAN is and how subnets are made…

If more IP of the same subnet are assigned to one bridge, is used only the IP with the less binary value.

Without other details… I’ve never read such bullshit…

Draw a network diagram, specify the equipment and point out where the bottleneck, we will suggest solutions.
I haven’t seen such a variant of channel aggregation yet … :open_mouth:

So you need to change the switch

if you notice, WAN is on ether2***, not SFP(+) or other gigabit port when routerboard has mixed 100/1G ports (like rb2011)…



***: or better, is one interface that the user call “Eth2”

More clearly state the requirements of user and device traffic required.
Its way to early to decide on subnets, brigdges etc when you havent defined clearly what traffic needs to flow

a. identify all the users/devices and groups of users/devices including the admin
b. identify all the traffic flows they need ( and what they dont need )

This time is hard… very hard… :mrgreen:

Your awake! I thought cats slept all the time. I see your fornicating ways have travelled the globe wasnt that your son I saw in another thread FROM AUSTRALIA…

Yeah, I'm the prettiest cat around here. Or is it the cutest? Well, definitely the nicest :laughing:

It would appear the orange cat has anger issues! :wink:

11

No anger issues … pure love. As you’re senior citizen with eye sight problems, here’s enlarged version of my avatar for you only:

12

can I provide this, for you?
is more clear…

13

Well … the senior citizen will have to tell if this version helps him in any way. On the other hand your version lacks the point of avatar … which is the cat saying “I love my computer” …

14

I understand… but even with a magnifying glass it is unreadable :laughing:

15

With proper cat vision it’s readable :stuck_out_tongue:

:wink: ?

This could work if you choose a Subnetmask with only a few hosts, for example 192.168.17.10/29, 192.168.17.20/29 and 192.168.17.30/29

What does that have to do with it?
The @villegas hex has all 1Gb ports. The reason why he cannot use the bandwidth of the wan port is only if the switch he is connected to has ports at 100 mbps. And he is trying to get a 3x100 aggregation this way.
But all this is just guessing on coffee grounds, until the @villegas gives full information

Tochno…

Another issue I have with el gatto arancione, is the sexisme… Why is the chainsaw assumed to be masculine :slight_smile:
Clearly Mkx has not heard of John Wayne Bobbit. :wink:
