@t-nelson , do we have a network topology for Colo captured in a diagram somewhere? Basically a wire diagram that has all network equipment (machines, switches, gateways) and the interconnectivity..

Problem
When passing the
-P
flag tonet/colo.sh create
, specifying use of public IPs, the following error occurs upon validator start up:Some experimenting with the
solana-ip-address{,-server}
progs from thenetutil
directory uncover the issue.1) Connecting to a
solana-ip-address-server
instance, using its public IP, from a host external to the Colo LAN, reports the expected external host's public IP.2) Connecting to the same server instance, this time using its private IP address from another host on the Colo LAN, again reports as expected, the client host's private IP.
3) Now connecting to the server from the same LAN host as in [2], but this time using the server's public IP, results in the connecting coming from the LAN gateway private IP.
Proposed Solution
I believe this is a network equipment configuration issue. I've opened a line of communication with the contractors who helped us with setup and am waiting for feedback.
