[libvirt] [PATCH 2/2] util: move firewall rules into per network chains



The previous commit created chains for each virtual network. This commit
adjusts the code so that rules are now put in these new chains.

With two networks running, the filter table thus looks like

  -N LIBVIRT_FWI
  -N LIBVIRT_FWI_virbr0
  -N LIBVIRT_FWI_virbr1
  -N LIBVIRT_FWO
  -N LIBVIRT_FWO_virbr0
  -N LIBVIRT_FWO_virbr1
  -N LIBVIRT_FWX
  -N LIBVIRT_FWX_virbr0
  -N LIBVIRT_FWX_virbr1
  -N LIBVIRT_INP
  -N LIBVIRT_INP_virbr0
  -N LIBVIRT_INP_virbr1
  -N LIBVIRT_OUT
  -N LIBVIRT_OUT_virbr0
  -N LIBVIRT_OUT_virbr1
  -A INPUT -j LIBVIRT_INP
  -A FORWARD -j LIBVIRT_FWX
  -A FORWARD -j LIBVIRT_FWI
  -A FORWARD -j LIBVIRT_FWO
  -A OUTPUT -j LIBVIRT_OUT
  -A LIBVIRT_FWI -o virbr1 -j LIBVIRT_FWI_virbr1
  -A LIBVIRT_FWI -o virbr0 -j LIBVIRT_FWI_virbr0
  -A LIBVIRT_FWI_virbr0 -d 192.168.0.0/24 -o virbr0 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
  -A LIBVIRT_FWI_virbr0 -o virbr0 -j REJECT --reject-with icmp-port-unreachable
  -A LIBVIRT_FWI_virbr1 -d 192.168.1.0/24 -o virbr1 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT

  -A LIBVIRT_FWO_virbr0 -s 192.168.0.0/24 -i virbr0 -j ACCEPT
  -A LIBVIRT_FWO_virbr0 -i virbr0 -j REJECT --reject-with icmp-port-unreachable
  -A LIBVIRT_FWO_virbr1 -s 192.168.1.0/24 -i virbr1 -j ACCEPT

  -A LIBVIRT_INP -i virbr1 -j LIBVIRT_INP_virbr1
  -A LIBVIRT_INP -i virbr0 -j LIBVIRT_INP_virbr0

  -A LIBVIRT_INP_virbr0 -i virbr0 -p tcp -m tcp --dport 53 -j ACCEPT
  -A LIBVIRT_INP_virbr0 -i virbr0 -p udp -m udp --dport 67 -j ACCEPT
  -A LIBVIRT_INP_virbr0 -i virbr0 -p tcp -m tcp --dport 67 -j ACCEPT

  -A LIBVIRT_OUT_virbr1 -o virbr1 -p udp -m udp --dport 68 -j ACCEPT

while the nat table has

  -N LIBVIRT_PRT
  -N LIBVIRT_PRT_virbr0
  -N LIBVIRT_PRT_virbr1
  -A POSTROUTING -j LIBVIRT_PRT
  -A LIBVIRT_PRT -j LIBVIRT_PRT_virbr1

  -A LIBVIRT_PRT_virbr1 -s 192.168.1.0/24 ! -d 192.168.1.0/24 -p udp -j MASQUERADE --to-ports 1024-65535
  -A LIBVIRT_PRT_virbr1 -s 192.168.1.0/24 ! -d 192.168.1.0/24 -j MASQUERADE

and the mangle table has

  -N LIBVIRT_PRT
  -N LIBVIRT_PRT_virbr0
  -N LIBVIRT_PRT_virbr1
  -A POSTROUTING -j LIBVIRT_PRT
  -A LIBVIRT_PRT -j LIBVIRT_PRT_virbr1
