No, your kernel IP routing table is incomplete (the default router/gateway is
missing, as shown in your NM run documented in your next post I asked you to do).

Add "option routers ...' to your dhcp config, but leave for now in there
"option classless-static-routes ..." to test and see how NM will handle it.
If it can not handle both in there, remove  "option classless-static-routes ..."
and test again.
It is quite possible that NM is buggy and you hit it.
Just do it one step at a time.

Can you give us a display of your DHCP config file (check where you have it ...):
# cat /etc/dhcp/dhcpd.conf
# cat /etc/dhcp/dhcpd6.conf
or describe it in any way possible what's in there ?

Btw, you have a sample of dhcpd.conf here on F14:
$ cat /usr/share/doc/dhcp-4.2.0/dhcpd.conf.sample
