Re: Linux and Inter-vlan Routing
Dear Bart-jan Thanks for attention.
I have correct my network configurations:
1) remove all interfaces on Debian except 1 interface
2) connect it to switch 2950 configured as Trunk
3)
#modprobe 8021q
#vconfig add eth0 2
#vconfig add eth0 4
4) vi /etc/network/interfaces
auto eth0
auto eth0.2
iface eth0.2 inet static
address x.x.x.x
...
auto eth0.4
iface eth0.4 inet static
address x.x.x.x
....
5) vi /etc/default/dhcp3-server
interface "eth0.4"
problems:
1)but my DHCP server don't Work!!! 0n eth0.4 interface.
2) Is the Vlan ID on 2950 same as on the vconfig?
3) My server require any patch?
best regards
