Hello
I have pppoe server with about 200-500 clients online - all of them
have public IP adresses and I use a "proxyarp" option in my pppoe
server what means the same as proxy_arp in /proc/sys/net but only for
my pppX interfaces (not for eth0, eth1 etc )
[...]
hey - i've found a nice arp setting : net.ipv4.neigh.eth0.base_reachable_time
from man 7 arp :
" Once a neighbor has been found, the entry is considered to
be valid for at least a random value (...) Defaults to 30 seconds."
My next questions :
- can I adjust it to be "0" - will it mean "infinite" ?
- why there's so short default time of re-sending the arp cache
refresh for and ip address ?
