                                              V
Netmask (bin): 1111 1111.1111 1111.1111 1111.1100 0000
Host    (bin): 1100 0000.1010 1000.0101 1110.1000 1100
Gateway (bin): 1100 0000.1010 1000.0101 1110.1100 0000
                                              ^

Note: The gateway is on a different network to the host.  The least
significant bit of the network address is different between the host IP
address and the gateway IP address.  So how do packets on the server on
network 192.168.64.128/26 network get to the 192.168.64.190/26 network?

You need to give your host an IP address on the 192.168.64.190/26
network (possible you meant to give it IP address 192.168.64.204
(1100 0000.1010 1000.0101 1110.1100 1100).  If you do this then you
won't need a route(8) config like I suggested in my earlier e-mail.
