No.
You have devices at .162 and .163, see the "via ..." bit here :

These addresses are also in the range you have specified so the server can attempt to give them to other clients. This is "a bad thing". So as a minimum you need to change your range statement to "X.X.X.164 X.X.X.190" - and if you have any other devices with addresses in that range then they need excluding too.

However, that still doesn't address your main problem. "unknown network segment" normally means that there is no subnet declaration which includes the IP address of the relay agent.
