RB SXT 5nD r2 - Cannot Get Traffic to Flow LAN/WLAN When Not Bridged

Hi,

I am having trouble getting traffic to flow between the LAN and WLAN ports of my RB SXT 5nD r2 (OS 6.27).

If I use the Quick Setup it configures a bridge and traffic flows fine.

The configuration I need to use is to have a firewall between the LAN and WLAN ports (making the LAN side the WAN or outside of the firewall and the WLAN the inside or safe side).

Please find below a dump of my config and I would really appreciate any suggestions - I am not even sure if OS licence level 3 (which is what comes on the SXT) has the ability to do what I want to do?

Regards,

Daniel Jansen

I eventually solved this one myself.

Turned out that I had forgotten to update the config under DHCP Server > Networks.

It was still set to 192.168.88.1 when it should have been updated to 192.168.1.1.
Traffic was then being filtered by the firewall which just required some tuning.

I blogged about my experience and solution here: http://blog.wdbb.com.au/cfml-mura-and-coding/mikrotik-rb-sxt-5nd-r2-cannot-get-traffic-to-flow-lan-wlan-when-not-bridged/
