There is nothing here to suggest a need for changing IP addresses. So this is most unclear. Stick with describing what you have and ask the first question by itself.
How can i connect to this network without changing all the IP addresses?
Each server talks to the other through static ip'sBut you don't say that these are public or private IP addresses. That's a big deal! So please tell us how the servers actually communicate: e.g.
Repeater - A wireless repeater with DHCP & NAT enabled, clients on different subnet from host AP (primary router). Computers connected to one router can not see computers connected to other routers in Windows Network.
When you get to a new location, you'll connect to the local access point, and the DDNS service will be updated with the new IP address. You can then use the DDNS node name to access the VNC repeater, and then get into any inside computer from there.
