Hi all,
I'm probably missing something rather obvious, but I can't get route
-iface to work. According to the manpage:
If the destination is directly reachable via an
interface requiring no intermediary system to act
as a gateway, the -iface modifier should be
specified; the gateway given is the address of this
host on the common network, indicating the
interface to be used for transmission.
I'm trying to get this to work on some 'real' system, but reproduced
on a couple of VMs to rule out other factors. I have two VMs on the
same host, connected by the same veb(4). Connectivity works if I use
IP addresses in the same subnet (i.e. I can ping from 10.0.0.1/24 to
10.0.0.2/24 if that's what I configure).
On one side I have:
test1# ifconfig vio0 10.1.1.13/24
test1# route add -iface 10.2.2.13 10.1.1.13
add host 10.2.2.13: gateway 10.1.1.13
On the other side, I have:
test2# ifconfig vio0 10.2.2.13/24
test2# route add -iface 10.1.1.13 10.2.2.13
add host 10.1.1.13: gateway 10.2.2.13
However, pinging from test1 to test2 gives:
test1# ping -c 1 10.2.2.13
PING 10.2.2.13 (10.2.2.13): 56 data bytes
ping: sendmsg: Invalid argument
ping: wrote 10.2.2.13 64 chars, ret=-1
--- 10.2.2.13 ping statistics ---
1 packets transmitted, 0 packets received, 100.0% packet loss
Yet the route is there:
test1# route get 10.2.2.13
route to: 10.2.2.13
destination: 10.2.2.13
mask: 255.255.255.255
interface: vio0
if address: 10.1.1.13
priority: 8 (static)
flags: <UP,HOST,DONE,STATIC>
use mtu expire
5 0 0
What am I doing wrong here? The destination *is* directly reachable
via an interface and the gateway given is the IP address of "this
host" on the common network, just as required by the manpage. At
least, my read of it .. since it doesn't work, I'm probably
misunderstanding something here.
I've enabled forwarding (net.inet.ip.forwarding=1) and disabled pf to
test if they were causing grief, but neither helped. Anyone have a
cluebat for me?
Thanks,
Paul 'WEiRD' de Weerd
