Re: [FW-1] slightly OT - multihoming (?)



A couple of principles that come to my mind are:
1. Put in the DMZ only those devices you want the public to see, use,
and (invariably) attack.
2. If you need a backup machine, it should generally be in a server farm
(not intended for public access) with copy or move mechanisms set up to
move data from the DMZ machines to the backup media.

What you have described seems a risky scenario to me...

Hello,

Sorry this is slightly off-topic, but I can't find any appropriate
information on the net.

I need to know how 'safe' mutlihoming a computer is....

Some of my collegues have built a backup computer (veritas software,
routing disabled - I hope!!) that has 2 NICs in it. One with an IP on
our public facing DMZ, one with an IP on our secure internal LAN. I am
strongly against this setup as I feel it compromises the security of our
internal LAN, but I can't find any information that will confirm or deny
this. Could someone please advise me, or know any where that I can find
some specific information on this?

Thanks in advance
