I've setup a DHCP server on my Debian server (Proxmox) so that I can provision IPs to my KVM guests on the server automatically. For some reason the DHCP server (isc-dhcp-server) isn't responding to requests for an IP. The DHCP server is set to listen to a bridge interface I've created called vmbr1 and I know requests are getting through to the host from the KVM guest as I've tested it through dhcpdump -i vmbr1.I've obviously made a mistake somewhere, can anyone spot it? I've included my configuration files below.dhcp.conf file:ddns-update-style none;deny declines;deny bootp;default-lease-time 600;max-lease-time 7200;log-facility local7;subnet 192.168.0.0 netmask 255.255.255.224 {     interface vmbr1;     option routers 192.168.0.5;     option broadcast-address 192.168.0.31;     option ntp-servers 192.168.0.101;     option domain-name-servers 192.168.0.101;     option netbios-name-servers 192.168.0.101;     option netbios-node-type 2;     default-lease-time 86400;     max-lease-time 86400;     #vmbr1ipv4      host 104 {hardware ethernet 1A:27:59:82:39:8E;fixed-address 95.141.36.124;}}isc-dhcp-server file:# Defaults for isc-dhcp-server initscript# sourced by /etc/init.d/isc-dhcp-server# installed at /etc/default/isc-dhcp-server by the maintainer scripts## This is a POSIX shell fragment## Path to dhcpd's config file (default: /etc/dhcp/dhcpd.conf).#DHCPD_CONF=/etc/dhcp/dhcpd.conf# Path to dhcpd's PID file (default: /var/run/dhcpd.pid).#DHCPD_PID=/var/run/dhcpd.pid# Additional options to start dhcpd with.#       Don't use options -cf or -pf here; use DHCPD_CONF/ DHCPD_PID instead#OPTIONS=# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?#       Separate multiple interfaces with spaces, e.g. eth0 eth1.INTERFACES=vmbr1interfaces file on host:# network interface settingsauto loiface lo inet loopbackauto eth0iface eth0 inet manualauto vmbr0iface vmbr0 inet static        address  95.141.36.188        netmask  255.255.255.0        gateway  95.141.36.1        broadcast  95.141.36.255        bridge_ports eth0        bridge_stp off        bridge_fd 0        network 95.141.36.0        bridge_maxwait 0auto vmbr1iface vmbr1 inet static        address  192.168.0.5        netmask  255.255.255.224        bridge_ports none        bridge_stp off        bridge_fd 0Example request from KVM guest to host server through vmbr1 using dhcpdump -i vmbr1:  TIME: 2014-05-28 21:40:14.232    IP: 0.0.0.0 (1a:27:59:82:39:8e) > 255.255.255.255 (ff:ff:ff:ff:ff:ff)    OP: 1 (BOOTPREQUEST) HTYPE: 1 (Ethernet)  HLEN: 6  HOPS: 0   XID: 599fa654  SECS: 0 FLAGS: 0CIADDR: 0.0.0.0YIADDR: 0.0.0.0SIADDR: 0.0.0.0GIADDR: 0.0.0.0CHADDR: 1a:27:59:82:39:8e:00:00:00:00:00:00:00:00:00:00 SNAME: .
