Default Route Blue, but can ping Default gateway?

RouterOS Beginner Basics
1

Ok guys i’m totally new at RouterOS so take it easy… I even read “Learn RouterOS” but i’m still lost :stuck_out_tongue:

I have a /26 of public IP’s i’m trying to pass to customers, see my crude network diagram attached :slight_smile:

My laptop on ethernet 2 of the RB750G actually receives the public address from the RB, but I cannot get online or ping anything… The RB can ping our DNS servers here, and the default gateway of 172.17.2.233.. But my default route shows up as blue like its inactive.. What am I missing here? I have a feeling its going to be something simple but i’ve been bashing my head for hours now! :laughing:

Thanks for your patience

Ok I tore everything apart over the weekend and was able to fix the default gateway issue… But I still cannot get online. My laptop is pulling a public IP 8.x.x.x and I can ping my mikrotik router, but nothing after that. The mikrotik router can ping the default gateway and also our DNS servers internally. Am I missing a simple firewall rule somewhere?

Post the output of “/ip address print detail”, “/ip route print detail”, “/ip firewall export”, “/ip pool export” and “/ip dhcp-server export”

Thanks for helping a newb out :slight_smile:

All that looks correct. I would remove the gateway check via ping from the default route - you have nothing to fall back to, so at best you risk false positives with that.

Otherwise you’re looking good on the RouterBOARD. If if it still not working I’d look at the core router. Does it have a route to the public IP space on ether2 via the ether1 IP address? Does the core route have any firewall rules that would block return traffic?

Your are correct sir, a route at the core router was fat fingered… there goes 15+hours of me bashing my head against the wall :stuck_out_tongue: Ty much for your input. On the bright side I learned my way around the RouterOS alot better :laughing:
