Nighthawk R6400 - Redirect outgoing IP address
I have a data logger on a local area network that sends data to a remote server for long-term storage. The company that provides the server and storage service is terminating support and will no long...

antinode,
Thank you again for your informative posts.
I have the skills to write the php script for a server to handle the handshake with the logger. In other packets that I captured I was able to see all of the details. It is a fairly simple handshake that is not quite trivial, but not that difficult to implement.
My issue is that the logger (my mystery device) points only at the fixed URL "gw1.eri-gw.com". This value is hard-coded. That is, there is no file that I can modify to have it point to a different URL. I found a backdoor GUI for the logger and was hoping that this would allow me to redefine the server URL, but it does not.
Not knowing much about routers, I was hoping that a typical router would keep a small domain name table within its local memory. If this were the case, it would seem that there might be a way to override the IP address that the router gets from its standard DNS. However, as I write this, I realize that this would probably present a security risk and so is probably not a control that a router manufacturer would make available.
Thanks

Some might. Even some Netgear models might. I've never seen a
Netgear model which allows the user to fiddle with anything of that
sort. Hence the suggestion of a local DNS server (or "hosts" file),
with which you _can_ fiddle. (A Raspberry Pi, for example.)
This kind of redirection stuff is not impossible, but getting a
consumer-grade Netgear router to do it might be tough.
The DNS processing in a typical Netgear router does intercept names
like "routerlogin.net", and deals with them internally, so it's not as
if the whole concept is foreign, but it's not intended to be
user-configurable. (And I know approximately nothing about the
details.)
If your R6400[vX?] allows you to enable Telnet access into it, then
you might be able to find a way poke something into it to get the
desired effect, but something like a firmware update, or even a restart,
might clean out any such modification. (And Netgear has crippled that
(undocumented) feature in recent R7000 firmware, too, so relying on it
carries its own dangers.) Everything's complicated.
