Hi,
I installed RouterOS 3.14 on RouterBoard 433 and configured it this way:
/interface pppoe-client add interface=ether1 user="myusername" password="mypassword" \
add-default-route=yes use-peer-dns=yes disabled=no
/ip address add address=192.168.0.1/24 interface=ether2
/ip firewall nat add chain=srcnat src-address=192.168.0.0/24 action=masquerade
/ip dhcp-server setup
My network looks similar like this, the difference is, that my adsl Modem works in bridged - mode, so ether1 is a pppoe-client:

I have three computers (all Win Xp) in the 192.168.0.0/24 network, two of them can connect to the internet, but my laptop can’t.
If I run ipconfig /all on my laptop, it says:
Ethernet adapter Local Area Connection:

The default gateway is missing.
When I remove the Mikrotik router from network and connect the computers directly to my adsl-modem (now configured as dhcp-server with network 192.168.1.0/24), then all computers can connect to internet.
Can somebody please help me to get my laptop connect to internet?
