MikroTik

Hi, i had a working network last week, then a friend came and helped me, now i have problems.

I have a HEX router connected to my ISP.
I then have a CRS326 connected to the HEX

I can ping from the HEX to the internet
I cannot ping from the CRS - pings to 8.8.8.8 timeout, DNS resolves,

Both config files are below

Any help greatly received.
thanks

I found the problem.

The NAT rule was using the WAN interface list. I changed this to pppoe-out1 and this seems to have resolved the issue.

I found this by going through the 'First time configuration' help pages one last time.

Why do you have an expensive managed switch but no vlans ????
Please send to me I will pay postage and send you a TPLINK managed switch

HEX
(1) Would remove this default DNS setting..

(2) If not using IPV6 disable it and can rid of all ipv6 firewall rules and address lists.

(3) I see nothing wrong on the hex so far...

CRS326
-Give the SWITCH a static IP address from the hex ( set static lease, and put it outside the pool, 192.168.88.5 for example.
-Leave the bridge mode to default = RTSP ( not none )
-Why is ether1 disabled?? Assuming ether2 is connected to HEX
-Assuming there is nothing plugged into ether1, and thus recommend configuring it from this port off bridge.
-Get rid of second route in orange, not doing you any good.

apologies I realise I didn't respond. Thanks very much Anav. I have a working network.

I smiled when I saw your comments around the use 326 and lack of VLANs - I will be adding vlans hopefully without support
