[pve-devel] [PATCH] add routed network mode

[Alexandre DERUMIER]

Seem that
enable_proxyarp($iface) 

is enough for me.


Indeed, we need proxy arp to get it work. (I have tested it).

I understand now,
as the tap interface is not plugged on a bridge, the tap mac address is unknown on the network.

So if an external client try to do an arp request : which mac has the ip X.X.X.X, I don't get any reply.
So we need to use proxy-arp, to get macaddress of host instead tap interface.

Do you really need proxy-arp on $external_iface ?

bug! We need to enable proxyarp on both sides: 

enable_proxyarp($iface) 
enable_proxyarp($external_iface)
