Hi there

I need some help!?

I have 4 x MikroTik 433 routers:

Router1 (Start Point):
LAN1 - Local LAN (192.168.0.1)
WLAN1 - Station (192.168.1.2)

Router2 (1st Hop) - Link distance 12km:
WLAN1 - AP-Bridge (192.168.1.1)
WLAN2 - Station (192.168.2.2)

Router3 (2nd Hop) - Link distance 22km:
WLAN1 - AP-Bridge (192.168.2.1)
WLAN2 - Station (192.168.3.2)

Router4 (End Point) - Link distance 6km:
WLAN1 - AP-Bridge (192.168.3.1)
LAN1 - Connected to ADSL router (192.168.4.1)

I need to get an ADSL internet connection running via Router4/LAN1. Multiple clients will connect through Router1/LAN1 with there individual PPPOE connections.

My questions (and current problems!):

1. From Router1 I cannot ping anything beyond WLAN1 of Router2 How do I need to setup my routes so that Router1 can ping straight through to Router4/LAN1?

2. I assume I'll also have to setup NAT on Router4/LAN1?

3. Do I need to do any further configuration to get the PPPOE connections working?

I'd appreciate any advice.

Thanks in advance.
 
You sound like a WISP? Have you attended any of the Mikrotik training courses? (incl the online ones?)
 
No, I'm not a WISP. I'm moving from Cape Town to a farm up north. Want to get ADSL running there ASAP... The only other (very bad and expensive) option was Satellite... Have not attended any coarses.
 
You mentioned "[their] individual PPPOE connections": so does that mean you'd like PCs connected to Router1 to be able to do ADSL PPPoE sessions (i.e. to SAIX or I.S.) across your routed network and through ADSL modem at Router4?

If so, I'm afraid that's not possible because PPPoE is a layer 2 protocol, and thus cannot be routed. The simplest solution would be to turn all your Mikrotik routers into bridges -- they'd need to bridge the LAN and WLAN (or WLAN1 and WLAN2, in the case of Router2/3) interfaces together. You'd only need one IP subnet for the entire network.

PPPOE is used for the assignment of IP addresses at a layer 2 level. This does not have anything to do with whether or not it can be routed. You cannot get a PPPOE address assigned from across a router (in the same way as DHCP assignment works), however once the IP Address is assigned it is fully routable as any normal IP address would be.

You definitely do not need to bridge all the routers, you just need a PPPOE server running on each interface that is handing out addresses.
 
Thanks for the info.

Thus, if I want to use Router1/LAN1 as the primary interface for PPPOE connections, I have to setup the PPPOE server on this interface? Is it difficult to setup this server? Any funny settings I must be aware of?

I'd also still like to know how I can setup the routing tables to communicate through all the routers?

By the way, what kind of pings am I suppose to get over 40km?
 
shrick - sounds like you need to do some reading or get to some training - the questions you are asking cannot be answered with a few lines. You will need a deeper understanding of how the router works first in order to get a setup like this working properly.

This is a ping over a 48km link using standard 65mW mini-pci cards and 31dB grids @ 5.8ghz

ping 10.2.16.1
10.2.16.1 64 byte ping: ttl=63 time=3 ms
10.2.16.1 64 byte ping: ttl=63 time=3 ms
10.2.16.1 64 byte ping: ttl=63 time=4 ms
10.2.16.1 64 byte ping: ttl=63 time=2 ms
10.2.16.1 64 byte ping: ttl=63 time=3 ms
10.2.16.1 64 byte ping: ttl=63 time=3 ms
6 packets transmitted, 6 packets received, 0% packet loss
round-trip min/avg/max = 2/3.0/4 ms
 
OK, I'll try to figure it out...

Any other important tips on getting such long distance links running smoothly and performing well, specifically on the software (ROS) side?

I'm using 31DBi antennas with 350mW cards for all sites.

Thx

The IP traffic encapsulated within PPPoE is certainly routable; but the PPPoE frames themselves (i.e. the Ethernet frames with ethertype 8663/8664) are not routable. So it's not possible to have a PPPoE session from a PC at the Router1 end of the network through an ADSL modem to a Telkom ADSL BRAS when there are routers in between.

However, if the assumption I made in my previous post is incorrect, and the ADSL PPPoE sessions will terminate in a NAT router at the Router4 side of the network, then it should be relatively simple to set up routing in the network with the appropriate static routes on the Mikrotik routers.

That's correct. PPP is a direct link between the two hosts, and seeing that it's L2, routing/IP's is still "unheard of".

My guess is that he simply wants to NAT internet access from an ADSL link on the last router. But like savagedavid said, your questions cannot be answered in one quick post

ah I have see many wireless networks that are bridged.. they work just "fine"
:D
 
quick question,if you use wds will your speed be slower and how much bandwidth drop?
and is it better to use a 433 board for voice than a 600 with 3 card on?
