No internet connection to LAN yet router connects

Sun Mar 03, 2024 12:42 pm

Hi all,

I have recently purchased an hEX router (RB750Gr3) and I'm having (noob) troubles configuring it. My home internet setup is as follows: I have a 5G FWA connection, my ISP installed a ZTE MC7010 on the roof acting as antenna and modem, from which I get an ethernet cable that is supposed to connect to the WAN port of the ISP provided router. I wish to get rid of the latter in favour of the hEX.

Connecting the router to the internet, starting from the default configuration of RouterOS version 7.13.4, was trivial: I just had to connect the cable from the ZTE antenna to port 1, create a VLAN with vlan-ID 1038 on ether1 as per the ISP recommendation and setup the DHCP client on the newly created vlan1 interface.

I can correctly ping, e.g. 8.8.8.8, from the router's tool, however all LAN ports are not connected to the internet. Nothing suspicious comes up to my (very) beginner's eyes, so I'm here for help. This is my configuration:

# 2024-03-03 11:06:00 by RouterOS 7.13.4
# software id = **ELIDED**
#
# model = RB750Gr3

This is mostly the default configuration with the just the additions mentioned above. Did I make any obvious mistake?
Thanks a lot to anybody willing to help!

Put vlan1 into the WAN interface list.

@tangent
More explicitly, OP now has:
/interface list member
add comment=defconf interface=bridge list=LAN
add comment=defconf interface=ether1 list=WAN
And should run:
/interface list member
add comment=myconf interface=vlan1 list=WAN
Is that right?

Thanks a lot! That was it! I did have the feeling it was something silly :roll:
