Hi,
I would like to configure a second sub/cloned interface on a FreeBSD =
5.3 system. I have read various bits
and pieces on the subject but I cannot ping (from another server) the =
second IP which I have configured.
The steps I took to achieve this are:
kldload if_vlan
ifconfig=20
ifconfig fxp0.1 create
# then add the IP to fxp0.1
# after which my interfaces look something like:
fxp0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=3D8<VLAN_MTU>
inet 10.10.10.1 netmask 0xffffff00 broadcast 10.10.10.255
inet6 fe80::203:47ff:fe71:21e7%fxp0 prefixlen 64 scopeid 0x1
ether 00:03:47:71:21:e7
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
fxp0.1: flags=3D8842<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::203:47ff:fe71:21e7%fxp0.1 prefixlen 64 scopeid 0x8
inet 10.10.10.2 netmask 0xffffffff broadcast 10.10.10.255
ether 00:03:47:71:21:e7
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
vlan: 1 parent interface: fxp0
>From this server itself I can ping the second IP 10.10.10.2, but from =
other systems I can only ping 10.10.10.1.
Im most familiar with Solaris and this type of config works no probs =
with Solaris, is there something else I
have to configure on FreeBSD? For example I found it wouldnt let me use =
the normal subnet and I then read
that for a second IP on the same subnet it should be set to -1
Any ideas? thanks for any help,
Andy.
