[Bug 723445] Re: iptables on virtual machines affect ghostified interfaces (eth42)

 

Well this problem is really difficult you want 
iptables -P INPUT DROP 
to not be able to filter eth42
We have no answer yet, sorry.
May be in a new revision of the ghostification kernel patch.

Title:
  iptables on virtual machines affect ghostified interfaces (eth42)

Status in Marionnet - A virtual network laboratory:
  New

Bug description:
  the traffic through eth42 (ghostified interface) can be affected by
  netfilter configuration.

  For example if a student blocks all incomming packets (iptables -P
  INPUT DROP) on a virtual machine it's no longer possible to connect to
  this machine with ssh using the eth42 interface.
