ifndp-proxy
IFNDP-PROXY(5) Network configuration IFNDP-PROXY(5)NAME
ifndp-proxy[-<interface name>] - IPv6 NDP and IPv4 ARP proxy entries
SYNOPSIS
/etc/sysconfig/network/ifndp-proxy
/etc/sysconfig/network/ifndp-proxy-<interface name>
DESCRIPTION
These files contain IPv6 NDP and IPv4 ARP proxy settings, that should be applied using the ip neigh add proxy command documented in the
ip(8) manual page that provides a common interface for IPv4 and IPv6.
The NDP/ARP proxy is required, e.g. when IP addresses from the same subnet have to be used on the interface of the host as well as on
interfaces behind a (tunnel) interface and using a bridge is not an option.
Don't forget to enable forwarding and the NDP/ARP proxy by setting
net.ipv6.conf.<all|default|interface name>.proxy_ndp = 1
net.ipv6.conf.<all|default|interface name>.forwarding = 1
and/or
net.ipv4.conf.<all|default|interface name>.proxy_arp = 1
net.ipv4.conf.<all|default|interface name>.forwarding = 1
or
net.ipv4.ip_forward = 1
either as global all setting in the /etc/sysctl.conf file or using the ifsysctl(5) files, that allow per-interface setup.
Forwarding can be also enabled in the /etc/sysconfig/sysctl file using the IP_FORWARD and IPV6_FORWARD variables.
The proxy entries are added and deleted using the if-{up|down}.d/ndp-proxy script, every time after an involved interface has been set
up or down.
SYNTAX
The format of the ifndp-proxy file is:
<address> <address interface> <proxy interface list>
The format of the ifndp-proxy-<address interface> file is same to above, but allows also to omit the address interface by using a "-" as
placeholder inside of the file, because it is already available in the file name:
<address> <address interface | -> <proxy interface list>
Lines beginning with # and blank lines are ignored.
Each line defines to add a proxy NDP/ARP entry with the address of or behind address interface to all interfaces in the proxy interface
list.
EXAMPLES
Let's assume, your machine is connected via eth0 to a switch with the networks 2001:db8:abba::/64 and 192.168.100.1/24 and is using the IP
address 1 itself. You'd like to use the addresses 11 and 12 e.g. for virtual machines behind the tap1 and tap2 interface, that is:
2001:db8:abba::1/64 -- local eth0 address
2001:db8:abba::11/64 -- address behind tap1
2001:db8:abba::12/64 -- address behind tap2
192.168.100.1/24 -- local eth0 address
192.168.100.11/24 -- address behind tap1
192.168.100.12/24 -- address behind tap2
then set up the following entries in the ifndp-proxy file:
2001:db8:abba::1 eth0 tap1 tap2
2001:db8:abba::11 tap1 eth0 tap2
2001:db8:abba::12 tap2 eth0 tap1
192.168.100.1 eth0 tap1 tap2
192.168.100.11 tap1 eth0 tap2
192.168.100.12 tap2 eth0 tap1
additionally to the routing entries in the routes or ifroute-<interface name> files.
