Problem with multiple ethernet interfaces
I have Debian 3.0 SPARC (woody) running on Sun Ultra 10 machine. Recently,
I have added an additional PCI NIC card. The card seem to be working
without problems and I have edited the file /etc/network/interfaces to
configure the second interface and now it looks like the following:
auto lo eth0 eth1
iface lo inet loopback
iface eth0 inet static
iface eth1 inet static
The execution of the route command, produce a result like the following:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.5.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
I have two subnets connected to two ethernet interfaces of a cisco router
192.168.1.0/24 and 10.5.5.0/24.
The problem that I have is that, I cannot access the 192.168.1.20
interface from the 10.5.5.0/24 subnet. Also, I cannot access the 10.5.5.20
interface from the 192.168.1.0/24 subnet. However, all machines in the
10.5.5.0/24 subnet can access the IP 10.5.5.20 and all machines in the
192.168.1.0/24 subnet can access the IP 192.168.1.20.
This only happens with this particular machine so it is not a router
issue. For all other machines, I can connect between 10.5.5.x to
192.168.1.x without problems. I even have a Windows 2000 Server with 2 NIC
cards one in the 192.168.1.0 subnet and one on the 10.5.5.0 subnet and
both interfaces are accessible from both sides.
Any help is appreciated!
Note: the actual subnet numbers are different.
