When in doubt, do it in binary:
0 =
64 = 0100
128 = 1000
192 = 1100
As a /26 (taking as given the 24 x's not shown for the other three octets):
xxyy - y's are the host
xx doesn't have the same value from 64-191
As a /25:
xyy - y's

No.
If so, why is this?
Because it there is no mask that will fit. In binary, you have:
0
63 0011
64 0100
127 0111
128 1
Hi all,
I have a really really really annoying problem that I'm trying to
rectifiy. I have three gateways, and two ipsec (esp encrypted) links, one of
which fowards traffic to the internet. I was provided half a class C (/25)
which I have split into 4 subnets of 32 addresses (30 usable).
I am c

You're a few years out of date on that one. Socket options shoul

You must have the networks connected (on the public side), but when
using IPSec your gif tunnel won't really be used. It is just sort of
a "placeholder" to get the routing correct.
It is not a good idea to use gifs in parallel with IPsec tunnel mode.,
to do this routing trick

x.x.x.64/26 + x.x.x.128/26
This cannot be written as a /25, and there is no netmask that would
match.

Is it not possible to subnet a C class into 3 nets, like
0-63
64-191 <-- Offending network (?)
192-255
If so, why is this?

You must have the networks connected (on the public side), but wh
Hi,
I had a problem with my virtual tunnel here, since i couldnt make 2 separate

Hi,
I've been reading about mbufs and how they're used for
holding network packets and socket buffers and the
output of 'netstat -m' for a idle machine I've here
made me curious about how FreeBSD handles it in -CURRENT.
Why is it using so many mbufs when it's idle? My
small kwnowledge doe
