I need separate 3 foreign machines (security reason - firewall between
subnets is required).
I cannot divide one 128 pubic IPs subnet...
Foreign machines have to use public IPs....

Ok...
My issuse: I cannot touch any IPs of any machine ....
Ah. Here in lies the rub.
how to do it? What is the best solution? (proxy arp, additional
routing table?)
Do you really need a new subnet or just a new physical network? If
the later is the case, add a new network card to the Linux router and
bridge that new card with the old card that the computers were on.
Once you have the bridge in place, move the IP address that was
assigned to the old network card to the bridge interface. This will
allow the old machines to function as they were as well as the
machines that you moved. If you do not want the old machines to be
able to talk to the ones that you moved, use an EBTables (Bridging)
rule to block traffic from passing from the old NIC to the new NIC
wile still allowing them to get to the router the way they need to.
This works *GREAT*! I have used it a lot of places and have been very
happy with the results.
