Hi,
My FreeBSD box is behind a nat box which acts as a DHCP server. DHCP has
been working great so far, but I'd like to allow ssh connections through
the firewall to my machine, so I need to move to a static IP address.
The thing is, I can't really find any help on doing this in the handbook
or anywhere else.
I've figured out (by reading rc.network) that I need to replace
ifconfig_xl0="DHCP"
with
ifconfig_xl0="{ifconfig args}"
in rc.conf, but as for what those args I'm not sure where to start. The
man page for ifconfig wasn't all that helpful.
Here's some info
%] ifconfig -a
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::250:4ff:fed9:a981%xl0 prefixlen 64 scopeid 0x1
inet 192.168.1.100 netmask 0xffffff00 broadcast 192.168.1.255
ether 00:50:04:d9:a9:81
media: autoselect (10baseT/UTP) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
faith0: flags=8000<MULTICAST> mtu 1500
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
gif1: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
gif2: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
gif3: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x8
inet6 ::1 prefixlen 128
inet 127.0.0.1 netmask 0xff000000
ppp0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
Now, for the panicky, overwhelmed-sounding questions:
How much of the info for xl0 needs to be specified in rc.conf? How do I
translate a 192.168.1.* address to IPv6? Do I need to?
Also, why do I have so many interfaces listed? Should I disable any? Are
there any security risks?
Thanks much
Mark
