What am I doing wrong??

We are trying to set up a new Gateway router (Mikrotik Cloud Core Router CCR1009-7G-1C-1S+) with our new upstream provider. From factory default we have done the following programing.

Update to version v6.39
Changed Password
IP> Addresses - Added an address with the following info. Address: XX.XX.36.1/22 Network XX.XX.36.0 Interface: ether7 (all of our network traffic comes to this port)

Added another IP with the following info. Address: XX.XX.111.238 Network XX.XX.111.237 Interface: Combo1 (this is our IP giving to us by the upstream provider. This goes out to a fiber connection)

IP> Routes we added a route with the following info. Dst. Address: 0.0.0.0/0 Gateway XX.XX.111.237 - reachable combo1 Type: unicast Distance: 1 Scope: 200 Target Scope: 10 Pref. Source: XX.XX.111.238.

It automatically added dynamic routes with the following info. Dst. Address xx.xx.36.0/22 Gateway: ether7 - reachable Type: unicast Distance: 0 Scope: 10 Target Scope: 10 Pref Source: xx.xx.36.1

Another dynamic route it added. Dst. Address xx.xx.111.237 Gateway:combo1 - reachable Type unicast Distance: 0 Scope: 10 Target Scope: 10 Pref. Source: xx.xx.111.238.

That is all we have changed from default out of the box config. We can open a new terminal window from winbox and ping 8.8.8.8 fine. but from a computer on the network on our IPv4 range (ex. xx.xx.36.51/22) we get Destination host not reachable.

Our upstream provider said they have our IPs set up in their routing table but I want to make sure I’m not missing something on our end before I go to them.

Is there something I’m missing to program here???

Do you have NATting (masquarade) for outgoing traffic ?
Do you have DNS and DHCP configured ?
Can you ping from terminal any host on WAN side with it’s DNS name ?
Could you send /export info ?
