DHCP with VLAN enable on WAN port
Ok, I have a T26P with VLAN 100 enabled on the WAN port. The WAN port is in DHCP. I see the phone doing a DHCPDISCOVER and my DHCP doing a DHCPOFFER but it just goes on and on like that and the phone never ACK the DHCP lease:

Aug 14 23:20:51 system dnsmasq-dhcp[14498]: DHCPOFFER(eth5) 192.168.100.248 00:15:65:3e:bb:82
Aug 14 23:21:11 system dnsmasq-dhcp[14498]: DHCPDISCOVER(eth5) 00:15:65:3e:bb:82
Aug 14 23:21:11 system dnsmasq-dhcp[14498]: DHCPOFFER(eth5) 192.168.100.248 00:15:65:3e:bb:82
Aug 14 23:21:15 system dnsmasq-dhcp[14498]: DHCPDISCOVER(eth5) 00:15:65:3e:bb:82
Aug 14 23:21:15 system dnsmasq-dhcp[14498]: DHCPOFFER(eth5) 192.168.100.248 00:15:65:3e:bb:82
Aug 14 23:21:18 system dnsmasq-dhcp[14498]: DHCPDISCOVER(eth5) 00:15:65:3e:bb:82
Aug 14 23:21:18 system dnsmasq-dhcp[14498]: DHCPOFFER(eth5) 192.168.100.248 00:15:65:3e:bb:82
Aug 14 23:22:00 system dnsmasq-dhcp[14498]: DHCPDISCOVER(eth5) 00:15:65:3e:bb:82
Aug 14 23:22:00 system dnsmasq-dhcp[14498]: DHCPOFFER(eth5) 192.168.100.248 00:15:65:3e:bb:82
Aug 14 23:22:01 system dnsmasq-dhcp[14498]: DHCPDISCOVER(eth5) 00:15:65:3e:bb:82
Aug 14 23:22:01 system dnsmasq-dhcp[14498]: DHCPOFFER(eth5) 192.168.100.248 00:15:65:3e:bb:82

I have tried an Aastra in the exact same configuration and it was able to get it's IP address off the DHCP server in the same VLAN...

I'm running firmware 6.70.0.140.

Any hints?

RE: DHCP with VLAN enable on WAN port
I have the same problem on the T20p. i have given up on dnsmasq and moved to dhcpd

got my configurations done in dhcpd and it's working like a dream. i had the same problem with a polycom and i had a atcom ip phone and that worked.

I didn't have any VLAN but give DHCPD a try. i still can't figure it out as i have other sites that use dnsmasq and they are all fine.

RE: DHCP with VLAN enable on WAN port
Hello all,
Do you want DHCP VLAN feature?
Could you try our V71 firmware to check whether fix the problem?
T26:
ftp://yealinkftp:yealinkftp@ftp.yealink.....0.140.rom
T20:
ftp://yealinkftp:yealinkftp@ftp.yealink.....0.140.rom
Thanks.

RE: DHCP with VLAN enable on WAN port
This is a basic function in our latest V71 firmware, you can upgrade to 28.71.0.155 on the T46G.
