Losing first few pings on an asymetric network

by Robert Rapplean   Last Updated June 25, 2018 17:00 PM

I have a set of CentOS 7 machines that all have two NICs, one connected to a subnet with a default gateway, one that is entirely self-contained. Network diagram

When I send pings from an internal node to another node in subnet 1 (with the default gateway), I have no problems. When I send pings from an internal node to another node in subnet 2, the first few pings get lost before it figures out how to send/respond to them. I think that this is a noob routing or metrics issue, but could someone give me more detail on where to look, or what to fix.
