Hi, I have a Cisco Small Business - RVS4000 and I'm trying to use it to connect a server to
a domain configured to use non-public (10.1.1.x) addressing.
Before I get into the details, I thought I should get a possibly-crazy question out of the
way first:
Is it possible at all to create a connection for a device configured with a static-public IP
address to a non-public domain?
The reason I'm asking is because the server I'm trying to connect has multiple addresses
for it's NICs and it's RAID controllers and it's a royal pain to change all those addresses.
Just wondering if it's even possible or I just need to plan on re-IP'ng my server.
Thanks!

Joe,
It appears you will need to implement Network Address Translation (NAT) [or possible Port Address Translation (PAT)] at the border - on the device(s) that sits between your Internet link and your internal devices.

Thanks Frank!
I don't know whether or not you have experience with the Cisco RVS4000:

In addition to VPN, it can act as a gateway or router. Do you think it would be capable of NAT'ng
to my server if I positioned it between my WAN and internal LAN? Just to be clear, my internal
LAN has a domain controller/dns/dhcp and a gateway but they're configured to use 10.1.1.x
addressing.
BTW - I won't need access to my server from the outside, I just need to be able to access it
from devices on my internal LAN.

Hi Joe,
If your RVS4000 doesn't support NAT/PAT, you could always implement a router on the external side of your RVS4000 and perform your NAT/PAT there. Your setup should accept egress traffic to be NATted.
