Simple config but Internet not working.

Wed May 29, 2019 2:01 am

Hi all, I'm replacing a Mikrotik Routerboard 1100AHx4 for a non-profit since they lost the password to the old one. I have general knowledge of networking but not specific to Mikrotik.
Network is just so for that I have bridged the router ports and set up DHCP. Port 1 I left with the default Mikrotik IP so it's not in the bridge and neither is the WAN port which is port 13. Problem is no Internet. When I connect the WAN port it becomes 'reachable' according to the router but no Internet. I tried pinging but no go so DHCP doesn't seem to be the issue. Other than that I just have a simple queue with PCQ to share bandwidth. Also using masquerade as I think I'm supposed to when running a private network behind a single public IP. Wondering if my routing table is wrong but I don't know.
Any thoughts would be much appreciated. The config is below:
# may/27/2019 21:56:13 by RouterOS 6.42.7
# software id = CKED-AUWZ
# model = RB1100x4
# serial number = 91D80AE30458

Try this
/ip firewall nat
add action=masquerade chain=srcnat out-interface=ether13WAN
Not related to connection problems, but You have very insecure firewall rules. In input chain You should block everything, allowing only needed inputs. Also, forward chain is empty.
