Ah, that may indeed be the problem. I'm a bit rusty with this stuff.
The CentOS box is doing IP forwarding, but that doesn't mean that it's
actually acting as a NAT? On the far end, 192.168.144.0/255 would
just use the default route, which is to the gateway for the network to
which the VPN is connected. There's no explicit route for my LAN

Well, yeah, that part I expected. I was presuming the return packets
would go back to the tunnel address, which would send them to my
server, which would then NAT them back to the original LAN source; but
maybe that translation isn't happening where I thought it was.
