Hi guys.

Im trying to setup a RB751U-2HnD with a double wan script (is actually the second mikrotik router i've gotta configure, so please be patient). The thing is im stuck at the pppoe configuration in the winbox's GUI. I searched among the forum and other webpages with tutorials and i cannot manage to make it work. It says the pppoe is connected but yet i cannot make the computers on my network browse the web via that interface.

Any help would be really appreciated.

Try uploading your config (output from /export compact) for people to comment.

How is your internal network configured?
Do you have interfaces bridged?
Did you create the needed NAT rules?
Share your config, so proper advice can be given

Thank you for your quick reply.

I'll attach the config file i made with "/export file=config".

About the interfaces bridged, i modified the default bridge and now it has ports 1, 2, 5 and wifi.

The port number 1 will be used for the dsl (pppoe dialup with username and password) connection, number 2 will be connected to another switch, number 5 will be set as dhcp and connected to another 3g dialup modem (movistar)

The NAT rules, no i did not create them, now that you say it, i'll (try to) do it.

Add a NAT rule to masquerade traffic that is leaving on the PPPoE interface. Then check what your routing table looks like when the PPPoE Client is running.

You should also delete the ether1 and ether5 interface from the bridge.
