First pppoe Connection

RouterOS Beginner Basics
1

I am trying to setup my first connection

I have the following hardware
Alvarion Breezemax3000 Wimax Unit
rb750g

I have setup a pppoe connection on the first interface apart from that the rb is setup as default…

My Connectiontio get to waiting for packets and just hand there?

Any ideas ?

Hi guys, I know my first question was not to well structured…

I have managed to get the pppoe connection working and I can ping the outside world from the router .. but not from the clients pc’s? and I cannot resolve a dns…

Does your network topology require NAT? Do you have NAT set up correctly?

That’s a stab in the dark. It’s hard to give specific help without details. It would be best if you could post a network diagram together with the configuration you applied.

You probably need to setup a src-nat masquerade rule under /ip firewall nat. I just setup a couple of PPPoE routers this week and forgot that once. It had me stuck for a few minutes until I remembered.

/ip firewall nat

add chain=srcnat action=masquerade src-address=10.100.4.0/24 out-interface=pppoe-out1

Something like this would work. Just substitute your src-address with the private ip range you’re using. It essentially tells your inside network to masquerade behind whatever IP the pppoe-out1 interface is using on the internet.

And did you configure DNS on either the router (/ip dns) or in the PPP profile?

Thanks for the replies guy I think i should have given some more info…

Alvarion Breezemax3000 Wimax Unit (Static Ip 192.168.254.251)
RB750G with standard settings
on wan port configured to static ip 192.168.254.4
DHcp sever running on port 2-5 router ip = 192.168.88.1

I have setup a pppoe connection Which allows me to ping the internet from the router.. when i ping from a box on port(2-5) the initial ping is very slow then all thereafter are fast)
It seem like a Dns issure..

When i use the Breese max without the router I set it as the dns server(192.168.254.251) and do a straight windows pppoe connection this works..
so when I use the router the Dns servers are 192.168.88.1,192.168.254.251


I have 2 nat firewall rules setup for masquerading


add chain=srcnat action=masquerade src-address=xxx out-interface=pppoe-out1
add chain=srcnat action=masquerade src-address=xxx out-interface=ether-gateway

Thanks guys I really appreciate the help

Ok so I have been playing about and I am not clear on a couple of things ?

The PPPoe Device is staticly assigned 192.168.254.251 with no option to change that and no DHCP server.

so I should connec this device to the RB750g on ether1-gateway. I should then setup ether1-gateway to have a static IP possibly 192.168.254.250?

Then create a PPPoe interface that used the ether1-gateway(default Route=yes;DoD = yes)


I should then setup the DHCP server on the other ports to sent out address in the rage on the router (192.168.88.10 - 192.168.88.255) or should i use the range 192.168.254.10 - 192.168.254.249) ?

Then the dns server should it be the router or the pppoe Device ? or the isp’s dns ?

Thanks
