A little off topic here... I'm spinning a "what if" to see if this is
possible and / or if anyone can offer suggestions regarding best
practices on setup.

 

I am attempting to setup a Multi-ISP (2 different upstream ISP's)
Shorewall in tandem with Bandwidth Arbitrator.
(http://www.bandwidtharbitrator.com
<http://www.bandwidtharbitrator.com/> ).

 

I would like to make this a single-box solution, so would love to
leverage Xen to host the VM for Bandwidth Arbitrator, as BA requires a
patched 2.6.5 kernel.

 

My configuration would look something like this:

 

ISP1     ISP2

  |           |

  -------------

        |

     DOM0------DOMU

                        |

     DOM0----------

        |

Internal Net

 

 

As the 2.6.5 DOMU in my config MUST be fully virtualized, I cannot use
pciback.hide to reserve a NIC in DOMU to be the gateway for my internal
network, so my idea was to arrange NIC's / virtual NIC's thusly:

 

ETH1    ETH2

   |           |

   -------------

         |

   Dummy0-----XenBR0

                          |----------bridged inside DOMU (BA works via
bridging only)

      ETH0-------XenBR1

         |

Internal Net

 

 

Is this theoretically / practically possible using Shorewall and Xen, or
am I just creating waaaaay to much work for myself?
