and now for today's question ;)
(i have looked in the handbook, the freebsddiary, and _the complete..._ by
Greg Lehey. It seems like a simple enough question, i'm just stuck)
Here is a diagram of the network as it is currently implemented (wrapped for
readability):
+==========+==========\
.130 .131 .129
+
.2
_____ /
Internet<==/_.1_/====+========
.33
.130 and .131 are on the internal half of the 255.255.255.192 subnet. The
gateway, which has two NICs and .129 on the internal one and .2 on the
external one *should* route packets. .1 is an ISDN routing device (no ppp,
dialup headaches, yay!) and .33 is a machine that is (currently) on the
external side of the gateway.
from .130 and .131 I can ping each other, .129 *and* .2 addresses, but *not*
the .33 or .1 addresses. from the gateway machine I can ping all addresses
on the network and internet.
I'm really not sure where to look first to make .33 and the internet
accessable from the internal machines. Eventually, the gateway machine will
be a firewall and NAT (and .33 will go to .133) but currently it is
installed with a minimal config, the source distribution, make, and bind
(bind is not yet configured).
So let's start with what is in my /etc/rc.conf file on the gateway:
# -- sysinstall generated deltas -- #
ntpdate_flags="ncar.ucar.edu"
saver="star"
blanktime="300"
gateway_enable="YES"
ntpdate_enable="YES"
network_interfaces="ed0 ed1 lo0"
ifconfig_ed0="inet 10.101.101.2 netmask 255.255.255.192"
ifconfig_ed1="inet 10.101.101.129 netmask 255.255.255.192"
defaultrouter="10.101.101.1"
#defaultrouter="NO"
hostname="panama.int.topsecret.net"
releaseName=""
#static_routes="route_int route_ext" #list of static routes
#route_int="-net 10.101.101.0 10.101.101.2"
#route_ext="-net 10.101.101.128 10.101.101.129"
as you can see, i've tried a few things already and the gateway_enable="YES"
*is* turned on. When I uncomment the last three lines I get errors in the
myst that goes by as the system boots, but it's at some point after what
shows up in /var/run/dmesg.boot
and here's what ifconfig -a shows me:
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.101.101.2 netmask 0xffffffc0 broadcast 10.101.101.63
ether 00:80:29:ef:61:71
ed1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.101.101.129 netmask 0xffffffc0 broadcast 10.101.101.191
ether 00:80:29:ef:81:d1
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
and, while i'm at it, here's a snippet from from:
http://www.ietf.org/rfc/rfc1878.txt that tells me that my subnetting isn't
screwed up...
Table 1-2 represents traditional subnetting of a Class C network
address (which is identical to extended Class B subnets).
Subnet Mask # of nets Net. Addr. Host Addr Range Brodcast Addr.
Bits of Subnet hosts/subnet
255.255.255.192 4 nets N.N.N.0 N.N.N.1-62 N.N.N.63
2 bit Class C 62 N.N.N.64 N.N.N.65-126 N.N.N.127
10 bit Class B N.N.N.128 N.N.N.129-190 N.N.N.191
N.N.N.192 N.N.N.193-254 N.N.N.255
any suggestions?
