Proxy ARP
=========

Public domain
********************************************************************************
### Minimal Example

    EXTIF="eth0"
    INTIF="eth1"
    INTIP="172.16.20.101"
    INTMASK="255.255.255.0"
    GATEWAY="172.16.20.2"
    NETWORK="172.16.20.0/24"

    route add ${GATEWAY} dev ${EXTIF}
    route del -net ${NETWORK} dev ${EXTIF}
    ifconfig ${INTIF} ${INTIP} netmask ${INTMASK}
    echo 1 > /proc/sys/net/ipv4/conf/${EXTIF}/proxy_arp

### General Example

    EXTIF="eth0"
    EXTIP="172.16.20.100"
    EXTMASK="255.255.255.0"
    INTIF="eth1"
    INTIP="172.16.20.101"
    INTMASK="255.255.255.0"
    GATEWAY="172.16.20.2"
    NETWORK="172.16.20.0/24"

    ifconfig ${EXTIF} ${EXTIP} netmask ${EXTMASK}
    route add default gw ${GATEWAY}
    route add ${GATEWAY} dev ${EXTIF}
    route del -net ${NETWORK} dev ${EXTIF}
    ifconfig ${INTIF} ${INTIP} netmask ${INTMASK}
    echo 1 > /proc/sys/net/ipv4/conf/${EXTIF}/proxy_arp
