RV320 dhcp and linux client

Hi,

We install a new network with a RV320, a HP switch 1910-8G and an access point TP-Link TL-WDR4900 which was our old routeur.

Main network is 192.168.1.0/24

We created 2 vlans, id 10 192.168.10.0/24 and id 20 192.168.20.0/24

Each windows or mac client connects to wifi ap with an SSID and a wpa2 key. RV320 is providing all informations related to the vlan, give an ip address with dhcp, give gateway and dns server. We do not have problems with thoses clients, like with tablets, iphone or android.

When we tried connection with linux client, it didn't work.

 

Here is the log with a archlinux client using netctl and dhcpcd client.

With wireshark we saw the dhcp request from linux to router, but we did not receive the ACK response.

 

We connect the linux client directly to the RV320 with an ethernet cable. And we retried to connect. Same issue.

 

If we configure the client connection with a static ip address 192.168.10.19, the router address as gateway and dns server 192.168.10.1, the client was connected and could browse the network and internet.

So we tried the same configuration with the wireless interface, and it worked.

We have 2 linux clients, one with archlinux, the other with ubuntu and we have the same effects. We can connect with static ip, but not with dhcp.

Any suggestions ? Thank you.

Hi,There is a bug in the dhcp

Hi,

There is a bug in the dhcp server of the RV320, it fails to attribute an ip if the dhcp client send an unknow dhcp client identifier. A solution is to set this id as an empty string like that :

vim etc/dhcp/dhclient.conf

send dhcp-client-identifier = "";
