DHCP not working on Wireless/Ethernet bridge

General questions

I have the following coniguration:

set service dns forwarding dhcp ‘br12’
set service dns forwarding listen-address ‘10.100.12.254’
set service dns forwarding name-server ‘8.8.8.8’

In the above setup I can successfully get DHCP leases on ethernet, but not on Wireless.

The only thing I can suggest is to state what version of Vyos you’re using - I’ve never used Wireless Interfaces directly on a Vyos device before I’m sorry so I can’t provide anything of use.

Hey, thanx it is:

Image version: VyOS v1.3.6
Release train: equuleus

Hi same with me like @tjh but I would say your config has a lot going on and maybe isn’t helping you with troubleshooting.

Can you simplify to just one wlan and eth device and see if dhcp is working before layering on the virtual and bridge interfaces?

5

Are you tagging traffic on your wireless device prior to connecting? If not, that could be your problem. My guess is you don’t actually want to do that, and should just have wlan12 as part of the bridge and not wlan12.12.

@tomasl I’d suggest removing the dhcp relay configuration.

set service dhcp-relay interface ‘br12’
set service dhcp-relay server ‘10.100.12.254’

Since the dhcp server is running on the router itself, there’s no need for a relay.

If your dhcp server was on a separate machine on say vlan10, then you’d need a relay defined with information for vlan10 to get the dhcp requests to the correct place.

You also likely do not need:
set service dhcp-server listen-address ‘10.100.12.254’
