Hi,

I´ve configured a relay (network lan - wan linux firewall). Devices in LAN should get ip addresses from Linux Gateway. OK

Additionally there is a guest subnet only for wifi (wlan0-1). OK

Therefore dnsmasq-dhcp should be used. NOK

Thu Sep  3 16:22:45 2015 daemon.info dnsmasq-dhcp[3529]: DHCPDISCOVER(wlan0-1) b4:ce:f6:08:da:bf
Thu Sep  3 16:22:45 2015 daemon.info dnsmasq-dhcp[3529]: DHCPOFFER(wlan0-1) 192.168.254.155 b4:ce:f6:08:da:bf

But no DHCPREQUEST !!

If I stop relayd, DHCP for guest is fully functional!

Firewall for testing disabled.

Thanks in advance for your help

Chris
