yes you can do that with minimal or no downtime at all.... as of the moment, i dont know the exact network topology that you have but ill give you a simple trick to solve your problem... the trick is that since you have a firewall/NAT installed already.. setup your new firewall/nat and installed it in your network... i assume that you know already how to NAT and how to route packets to other network segments... now the scenario is that, a packet is going to and back from the internet is NAT (old firewall/nat server) by another NAT (new firewall/nat server).. dont worry about NAT by
but how will the new firewall/NAT be transparent so that my old (all-in-one)machine can still be known publicly? The new firewall/NAT has also a public IP in the same network with the old machine.
another NAT.. what important most is that the end-to-end communication is working perfectly fine.... after you did that, you can easily remove the configuration of your old firewall/nat server so that there will be one firewall/nat server left inside your network and that is your new fireall/nat server :->
ya, i'll be glad when this will work out fine...
Thanks.
