No DHCP in VLAN subnets when GeoIP filtering is enabled #8

Open LUFEZ opened 3 years ago

LUFEZ commented 3 years ago

I have multiple subnets and VLAN that the UDMP manages. UDMP is running with firmware 1.8.6

My subnets: 192.168.1.0/24 Management (no VLAN) 10.0.10.0/24 Main VLAN 10 10.0.20.0/24 IOT VLAN 20

After booting the custom kernel everything works. Traffic between subnets and Internet works. IPTV works.

The only thing that does not work is the DHCP address assignment in the subnets with VLAN. The clients do not get an IP address. Clients from the subnet without VLAN get an IP address. After restoring the stock kernel it works.

I use: udm-kernel-tools_1.0.0_arm64.deb udm-kernel-4.1.37-edge1_4.1.37-edge1-1_arm64.deb

What I don't understand, what do I need to do with the packages from pve-edge-kernel?

Any ideas what the problem with DHCP could be?

fabianishere commented 3 years ago

The reference to pve-edge-kernel is incorrect, I did not update the link to refer to this project.

As for the DHCP issue, I suspect that it is related to the firmware version 1.8.6 you are running. For example, there might be a small chance that the kernel for 1.9.0 is not compatible with firmware version 1.8.6.

I am currently on 1.9.3 and cannot reproduce the issue. Does /var/log/messages mention anything about dnsmasq?

LUFEZ commented 3 years ago

First of all: It works now! :)

In the log I see that there is a problem with GeoIP filtering and therefore all DHCP servers are stopped. I disabled GeoIP filtering in the settings and after that DHCP works.

With enabled GeoIP filtering:

Thanks for this great project. 👍 I think this will help many users who use UDM and IPTV.

Great to hear!

I wonder why iptables-restore fails when enabling GeoIP filtering though. I suspect it may be related to some changes Ubiquiti did to the netfilter implementation from 1.8.6 to 1.9.0.
