Mikrotik Repeater Setup help

[hilton]

What is wrong to bridge everything?

When you bridge you effectively create a very large LAN. This becomes a single broadcast domain so all unnecessary traffic that is normally not routed is now suddenly floating across your WAN. It will become very slow and when it breaks it will be a bugger to track down the culprit.

Routing is far more efficient in terms of protocol traffic.

Make sense?

You beat me to it Hilton.

FrOst, any news?

Hey there, sorry for the wait. Was trying some of the wiki stuff.
Yes i will be connecting to a Telkom dsl line, think its a linksys dsl router.
Yes i use it as a router . Modem>>……ethernet……. <<Ether1-RB411AH-Wlan1>>……5.8ghz……<<Wlan1 – RB433 – Wlan2>>……5.8ghz….<Wlan1 – RB411AR- Wlan2>>……2.4ghz <<laptop>>

This Mikrotik thing is really complicated.

Thanx portcullis appreciate the help.

 

[Fr0sT]

Is there a way to export or print all the setting that has been entered in to the routerboard?
If u maybe want to save the configuration ?

The Linksys will probably have an IP address of 192.168.1.1/24

In other words 192.168.1.1 mask 255.255.255.0

So, the first thing you are going to do is allocate an IP address to ether1 on Router B.

That IP address will be 192.168.1.2/24

In Winbox: IP - Addresses - "+" - 192.168.1.2/24 - make sure ether1 is selected from the drop down box and press OK.

You now need to add an IP address to the radio.

Assuming you have the link side of things working.... If not, that's a story for another post.

IP - Addresses - "+" - 192.168.2.1/30 - make sure wlan1 is selected from the drop down box and press OK.

IP - Firewall - NAT "+"

• General - Chain - sourcenat
• General - Out Interface - ether1
• Action - Action - Masquerade

Press OK.

IP - Route - "+"

Add the following routes

0.0.0.0/0 gateway is 192.168.1.1
192.168.2.4/30 gateway is 192.168.2.2
192.168.2.8/30 gateway is 192.168.2.2

Now let's go and play with Router C.

wlan1 connects to Router B
wlan2 connects to Router A

IP - Addresses - "+" - 192.168.2.2/30 - make sure wlan1 is selected from the drop down box and press OK.

IP - Addresses - "+" - 192.168.2.5/30 - make sure wlan2 is selected from the drop down box and press OK.

IP - Route - "+"

Add the following routes

0.0.0.0/0 gateway is 192.168.2.1
192.168.2.8/30 gateway is 192.168.2.6

Moving on to Router A

IP - Addresses - "+" - 192.168.2.6/30 - make sure wlan1 is selected from the drop down box and press OK.

IP - Addresses - "+" - 192.168.2.9/30 - make sure ether1 is selected from the drop down box and press OK.

IP - Route - "+"

Add the following routes

0.0.0.0/0 gateway is 192.168.2.5

Add the following IP address to the PC

192.168.2.10 mask 255.255.255.252
Gateway - 192.168.2.9

DNS servers - use Google, openDNS or your ISPs DNS servers.

We're done. Let's download stuff!

Hey there portcullis, thanx man it works.

The only thing is u must be able to connect to 411ar 2.4 GHz but i figured that one out. Thanks allot for all your peoples help especially portcullis, you helped me allot to make this link possible.


Now too get the antennas up on the high sites, I’ve seen the thread about the 27db and 31db.
I got the 31db for the 11km link don’t hope it was a bad choice and struggle to much to get it to work or align? :wtf:

Thanks again @ all

Hou die blink kant bo haha

 

[portcullis]

Those 31dBi antennas are really difficult to get right. I've got two that I want to use as braais. I had them running with R52H on an 8km link and never got more than 6Mb throughput. I've replaced them with two Poynting 23 dBi panels connected to F50Pro radios and the link's transferring data at 48Mb as I write this.

 

[Fr0sT]

6Mb it okay as long as it doesn’t disconnect or something, as I’m only using it to share internet.
How can i check the transfering speed between 2 sites?

 

[portcullis]

Winbox - Tools - bandwidth test on one side.

Make sure Winbox - Tools - btest server is enabled on the other side.

There's also a little btest.exe that can be downloaded from the MikroTik site to test from your pc.

I have a question for PortCullis. 192.168.2.4 and 192.168.2.8 is not set to any interface anywhere? Its entered in a static route but the ip addresses arent set in the diagram.

 

[portcullis]

Peon,

I'm using subnets.

http://www.ralphb.net/ipsubnet/

Or even better: http://www.subnet-calculator.com/

Each subnet of four IP addresses has two addresses that can be allocated to network interface cards, one network address and one broadcast address.

192.168.2.4 is a network ID, as is 192.168.2.8

 

[Peon]

I understood that yes I forgot you setting one logical domain between 2 points. Between B and C - 1 logical domain/subnet - 2 hosts 192.168.2.1 and 192.168.2.1

The same between C and A and then between A and the last router. 2 Hosts per domain/subnet. Cool man, thanks I get it now.

 

[Fr0sT]

Just want to know about grounding the routerboards.
Must the Routerboard be grounded to the antenna pole or is this not necessary?
Because the 411AR came with grounding cable to the enclosure and the routerboard, but the 411AH and 433 routerboard is mounted only on plastic and no grounding. Must I provide a ground for them or must I remove the ground cable from 411AR? Or does the POE provide ground to the Routerboards?

 

[portcullis]

Use only STP / FTP.

Make sure that the shield / foil is in fact connected to the connector and the connector is in fact a STP connector.

Assuing we're talking a Poynting type enclosure, the board gets earthed to the enclosure on the inside. I always run separate earth wires all the way into the ground.

I also use APC lightning protectors inside the building. Both in the patch panel and at the pc's, but that's just me and I like doing things right.

I also earth all network cabinets to earth rods outside the building.

No doubt there are those who take shortcuts who'll tell you that it's OK not to ground the stuff.

This may or may not change your mind.

Geez,sounds like you guys get a lot of lightning that side!

No we don't. But you forget that I used to own one of the first WISPs in Africa that I started in Zimbabwe in 1997.

Hey frost , i have had a similar problem like you and i ended up doing a EOIP set up between my two sites with no routing i managed to have the two site able to ping
each other.Have you tested if the set up would work doing a EOIP set up.........

I'd love to see the setup for each of the three routers.

 

[Fr0sT]

Not sure about the EOIP thing im new to Mikrotik, its awsome but complicated

 

[Fr0sT]

At what should i set the TxPower and Antenna Gain or must i leave them as they are?
