Hi,
Here might be a better drawing (possibly)
Router (10.0.0.2)
|
|
FreeBSD Gateway (10.0.0.1)
|
|
Switch (10/100)
|
------------------------- (10.0.1.0/24)
| | |
Laptop Desktop Wireless AP
The router is in bridge mode and my FreeBSD box gets its tun0 IP from DHCP
from the ISP through pppoe. The 10.0.0.1 is a static address and all the
machines (excluding the wireless), are dhcp in the 10.0.1.0/24 range.
I removed the read IP addresses from the post, I replaced them with x.x.x. I
howevere don't feel that the PPP is the problem because it is working for
about 5-10 minutes. Then everything stops working. Like an ARP problem. Cant
explain why I would have an arp problem though. I am not trying to configure
ppp as that works fine, its just that the network stops working after 5-10
minutes that its already working.
Cheers
Ian

Need more background info.
Explain where you are getting the public non-routable 10.0.0.0 ip
address from.
You say the ADSL router is using them.
Did you edit your real ip address to hide then from this public
post?
Also you have to post your ppp.conf file.
Are you trying to configure PPPoe?

Subject: Ethernet Stopping Problem
Hi,
I have a freebsd 5.2 box setup as my gateway for my home network.
The
network is layed out as follows:
FreeBSD Gateway - 10.0.0.1/16
ADSL Router - 10.0.0.2/16
DHCP Network - 10.0.1.0 - 10.0.1.254 all /16 with default gateway as
.1
I have ppp enabled on the freebsd unit, and it connects fine and
then
everything works perfectly for anything between 5 and 10 minutes. At
this
stage, the freebsd machine cant get to the 10.0.1.0 network anymore.
It can
still ping 10.0.0.2 fine and its connection to the internet remains
perfect.
It just wont let anyone else come in from anywhere else on the
network. It
kills all SSH sessions, web sessions etc. I replaced the ifac card
with an
ed0 card, and also replaced cables and the switch in between.
The card in question is both a dc0 and an ed0 card which I have
swapped into
another PCI port and it still does the same thing there. Below is an
ifconfig:
ed0: flags=108843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.1 netmask 0xffff0000 broadcast 10.0.255.255
ether 00:c0:df:fa:b8:74
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1492
inet 165.x.x.x --> 165.x.x.x netmask 0xffffffff

I don't have any sysctl rules in place, and everything else about
this unit
is standard.
I am not running a firewall at this stage and was just wondering
what the
cause of this problem could be?
Cheers
Ian
