I haven't tried the latest client, but the prior one wouldn't set a
gateway for me on a Windows network, though apparently did on a Linux

It's common for a x.x.x.255 IP address to be a broadcast address, though
it doesn't have to be (there are other preconditions). Some things do
seem to have problems with .255 ending IP addresses, even when they're
not a broadcast address. For that reason, it can be advantageous not to
use them. You may, later, discover even more problems than than the one
that you've just noticed.
A x.x.x.254 is a common convention for a gateway address, but it's just
a custom, there's no obligation.
Don't send private replies to my address, the mailbox is ignored.
I read messages from the public lists.
