This sounds like it *might* be something that I've mentioned at least
once, possibly twice, within seeming appropriate threads.
In the case I'm thinking, it's about manually adding multiple lines to
a file that I'm not completely remembering just now. Gut is saying
it's /etc/network/interfaces. Mine's almost empty so I don't have an
example to confirm that.
What I encountered wasn't about declaring different values for
gateway, either. For whatever reasons due to innate [functionality],
it becomes a fail even if you declare the same gateway value for that
line within each new, separate block of declarations. Success is found
by declaring it once then omitting that line within any other new
blocks added over time.
Between my setup and cognition, I've never had anything stable enough
to test if it matters which block that gateway is declared. I've
wondered if it matters that it be in the first block, or if it just
needs to show up somewhere in that file. I was consciously putting it
in the first block because that seemed to be the *logical* thing to do
k/t having touched on programming 20 years ago at a local tech school.

Just thinking out loud...
