CCR cannot perform routing

RouterOS General
1

Hi experts..,

I have a Mikrotik project for my customer… CCR1036-8G-2S+, currenlty using ROS 6.15.
I use this device as DHCP server and router. I configure vlan, vlan ip address, route/default gateway, dhcp server. After finish the configuration, the device cannot forward my traffic from LAN to WAN/Internet.

  • from mikrotik I can ping internet
  • from mikrotik I can ping endpoint in LAN site
  • my traffic from LAN can NOT goes to internet..

anything that I missed in the configuration ??

The connections below:

LAN1 — — — ------ [internet]
| |
LAN2 — — – |
|
LAN3 — --------

  • there are VLAN in each switch access (management vlan and traffic vlan)
  • swtich core iface and mikrotik iface already tagged
  • IP address for each vlan is in mikrotik (as gateway)


    Thank you

Daniel Hadi

Are you using RFC1918 addresses on the LAN? If so, did you configure NAT?

Sounds like maybe you forgot srcnat masquerading for your wan connection. Put your config up here and ppl will be able to assist

I’m sorry… additional information…, the internet connection (NAT) handle by other devices in HQ. SO this CCR only do routing.

Do you have any filters set on the forward chain in /IP Firewall?
