Hi all,
I'm having a bit of a problem setting up a FreeBSD-machine to connect two
LAN's. The situation is as follows:
|-------| |-------| |-------|
|Pentium| | DX2-66| | DX2-66| (10 machines)
| 66 | | | | |
|-------| |-------| |-------|
| | | |
\--------------/ \--------------/
ethernet ethernet
So the middle machine has TWO ethernet-cards to connect the two networks.
The most left network is a very small network with only one server, but
there will be more machines on that LAN in the near future. The most right
LAN is our own office LAN where the normal working stations are.
The problem is in the gateway:
I have two NE2000 Plus - Eagle cards:
ed0: addr.0x280, irq 10
ed1: addr.0x300, irq 11
Every time I boot FreeBSD I have to start with /kernel -c and type:
irq ed0 10
irq ed1 11
to set up the ethernet cards. I would have to rebuild the kernel to get
these setting permanent. Is there any FAQ or something about rebuilding the
kernel??
But the real problem is as follows:
I type
ifconfig ed0 up
ifconfig ed0 193.78.175.2
ifconfig ed1 up
ifconfig ed1 193.78.175.3
I get: "ifconfig: ioctl (STOPCAIFADDR): File exists"
So something went wrong configuring the second ethernet adapter. But I trief
"ifconfig -a", and got:
ed0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 193.78.175.2 netmask 0xffffff00 broadcast 193.78.175.255
ether 00:00:1b:4f:b9:38
ed1: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 193.78.175.3 netmask 0xffffff00 broadcast 193.78.175.255
ether 00:00:1b:4f:bd:fc
lp0: flags=810<POINTOPOINT,SIMPLEX> mtu 1500
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 65532
inet 127.0.0.1 netmask 0xff000000
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
sl1: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
So it seems like both ethernet cards are configured.
When I look at the routing ("netstat -rn"), I get:
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
127.0.0.1 127.0.0.1 UH 0 0 lo0
193.78.175.1 8:0:0:19:67:32 UHLW 0 1430 ed0 195
193.78.175.2 0:0:1b:4f:b9:38 UHLW 1 8 lo0
224 link#1 UCS 0 0 ed0 -1005
There is no route to all the working stations (193.78.175.0), so I try to
add this route ("route add 193.78.175.0 193.78.175.3"). After this when I
look at the routing table:
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
127.0.0.1 127.0.0.1 UH 0 0 lo0
193.78.175 193.78.175.3 UGSc 0 0 ed0
193.78.175.1 8:0:0:19:67:32 UHLW 0 1442 ed0 182
193.78.175.2 0:0:1b:4f:b9:38 UHLW 1 8 lo0
224 link#1 UCS 0 0 ed0 -1018
As you can see the route to 193.78.175.0 goes via 193.78.175.3, but the
interface is ed0 and not ed1!!! So I deleted the route and tried to add the
route with a specific interface ("route add -interface ed1 193.78.175.0
193.78.175.3"), but the systems hangs for a while and then:
"ed1: bad value"
So it seems like ed1 is not configured. Also because it is not added to the
route table with the ethernet-address like ed0 is.
When I try to ping the Pentium (193.78.175.1) it works and the Pentium can
ping the gateway. But when one of the workstations on the second LAN tries
to contact the gateway, the gateway just reboots!!!!
Does anyone know why ed1 was not configured correct and how I can rebuild
the kernel with the right settings (irq's)???
Thanks!
