Hi, I seem to be having a sort of weird networking problem.
First, I will describe the way the network is setup. (xxx represents
what i left out for security sake)
My upstream provider provides access through a ethernet connection. To
this particular ethernet connection, it has a IP address of
207.xxx.xxx.27. And to this IP, all of my subnets are forwarded to.
The setup for that ethernet card looks like :
ed1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 207.228.xxx.27 netmask 0xffffff00 broadcast 207.228.123.255
ether xxxxxxxxxxxxxxxxxx
There is a second ethernet card in the computer as well. This is where
I list the machines local IPs on the subnets that are forwarded to the
above IP. Also, the other machines on the network are connected to this
interface via some hubs. The setup of that ethernet card looks like :
vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 207.148.xxx.50 netmask 0xfffffff8 broadcast 207.148.xxx.55
inet 207.148.xxx.51 netmask 0xfffffff8 broadcast 207.148.xxx.55
inet 207.148.xxx.52 netmask 0xfffffff8 broadcast 207.148.xxx.55
inet 192.168.0.4 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:80:c8:e1:47:b2
media: 100baseTX <half-duplex>
supported media: autoselect 100baseTX <full-duplex> 100baseTX
<half-dupl
ex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 10baseT/UTP
<half-duplex>
And the machines on the network have IPs 207.148.xxx.5x and so on...
Everything seems great so far. From the outside world, people are able
to access the web servers running on .50, .51, .52 and I am able to
access them anywhere on the network as well.
However, on the machine that has those 3 IPs, it is only able to access
.50 itself! .51 returns HOST IS DOWN and .52 doesnt do anything when
trying to ping or access them via http. Like I said earlier, any other
machine in the world is able to ping and access these IP EXCEPT for the
machine that has them!
I think it may be something to do with my routing. Here is what my
table looks like right now.
Internet:
Destination Gateway Flags Refs Use Netif

gen<bbb>ip1.cadvisio xxxxxxxxxxx UHLW 116 0 ed1
418
gen<bbb>ip27.cadvisi xxxxxxxxxxx UHLW 0 2 lo0
If anyone has any ideas what might be causing this problem, please tell
me. I have been trying to figure it out for the last week and haven't
got anywhere with it yet.
Thanks.
