Re: Iptables and vlan interfaces

[Aseem Rastogi <aseem@india.tejasnetworks.com>]

i have been following this post rather keenly. it now seems to have died 
down. but still i am not able to understand what is a vlan interface. 
can somebody please give me some pointer where i can read about this. 
vlan i thought is a l2 concept and should have nothing to do with l3.

thanks in advance.

regards,
aseem.
