Problem connecting mikrotik router with broadband connection

RouterOS Beginner Basics
1

I have mikrotik router 750GL, broadband connection and username & password from broadband provider for PPPoE connection. I tried this link http://wiki.mikrotik.com/wiki/Manual:Interface/PPPoE to setup PPPoE client in Mikrotik router.

/interface pppoe-client 
  add name=pppoe-user-mike user=user password=passwd interface=wlan1 \
  service-name=internet disabled=no

I plugged in broadband wire in first port of mikrotik router and LAN cable in the second port for systems. I used above mention code to setup PPPoE client. After i set this setup, I monitored the status of this interface it shows

waiting for packets…

In the Log

pppoe-out1: initializing..
pppoe-out1: waiting for packets...
pppoe-out1: dialing....
pppoe-out1: terminating... -disconnected 
pppoe-out1: disconnected

How can I solve this problem?

The issue is that you setup the PPPoE on the wireless interface then plugged the internet connection into a wired interface.

Edit the PPPoE Client and change the interface to match the interface that the broadband provider is plugged into. The script you used must have been for having the PPPoE over the wireless and your using the wireless for internal connections.

The proper PPPoE setting is probably:

/interface pppoe-client
  add name=pppoe-user-mike user=user password=passwd interface=ether1 service-name=internet disabled=no

You can easily change this with winbox or the web interface.

I tried as you said but no luck. Is there any way to make it work?

Try to not set anything on the service name as many providers has a problem with it.

Thank you all guys for reply I got connected to broadband, I confirmed it as

interface pppoe-client> monitor pppoe-out 
          status: connected
          uptime: 13m17s
       idle-time: 2m41s
    active-links: 1
    service-name: 
         ac-name: ser-8-G61BQ251
          ac-mac: 00:30:88:1F:5B:B3
             mtu: 1480
             mru: 1480
   local-address: 106.51.134.124
  remote-address: 106.51.128.1

Now I see the broadband is connected to mikrotik router, but I don’t get internet to my system. In Mikrotik router I have added address for LAN systems as

/ip address> print 
 #   ADDRESS            NETWORK         INTERFACE
D   106.51.134.124/32  106.51.128.1    pppoe-out
     192.168.2.1/24     192.168.2.0     ether2

the first one is the address for WAN has created in address list when I get authenticated from broadband provider. In the interface pppoe-client is

>interface pppoe-client print 

 R name="pppoe-out" max-mtu=1480 max-mru=1480 mrru=disabled interface=ether1-Input
      user="username" password="pass" profile=default service-name="" 
      ac-name="" add-default-route=no dial-on-demand=no use-peer-dns=no 
      allow=pap,chap,mschap1,mschap2

Then I have connected my system over LAN to mikrotik router’s second port and assigned my system a IP as

IP:192.168.2.10
subnetmask: 255.255.255.0
default gateway: 192.168.2.1
preferred DNS: 192.168.2.1

After these setup I don’t get internet connection for my system. There is an exclamatory symbol on the internet icon.

You have to change the pppoe iface and modifiy add-default-route=yes then add a masquerade in your firewall

/ip firewall nat
add action=masquerade chain=srcnat out-interface=pppoe-out
7

Should I change pppoe iface, you mean interface?. It is already set to ether1-Input where I connected broadband cable(connected to first port of mikrotik router).

8

Set that option to yes in your pppoe-out interface

I have done set as you said. now from my system I can able to ping 8.8.8.8, but when I try to open www.google.co.in in my browser the page is not working.

If you want to use your isp dns be sure that use-peer-dns is checked or add it manually use-peer-dns=yes in the same way as the default-route option. If you want your own/google dns then set them on the dhcp server if you have one or from webinf ip-dns/manually

/ip dns
set allow-remote-requests=yes servers=ip
11

Also be sure you only answer DNS requests to internal machines. People scan for open DNS servers and use them for DNS amplification attacks.

/ip firewall filter add chain=input in-interface=all-ppp protocol=udp port=53 action=drop comment="Drop DNS requests from PPP Connection"

I didn’t test the above line so it could have a typo… basically in the input chain drop UDP 53 from your internet interface. However even better would be to accept only the services you offer (which may be noting or just access to your router with winbox) and drop anything else. If you have other interfaces that connect to the internet then you will need to drop DNS on all of them which could take more then one rule.

Thank you all guys. Finally I got it work by change DNS address in my system to ISP DNS.
