I'll try to be clearer. Please excuse me if you understood me previously, but from your last post I think you may still be confused.
Your dhcp.conf last posted above was pointing to the
WRONG SUBNET.
None of the 192.168 addresses referenced in that configuration file are valid. All of them must be in the range defined by your athn0 subnet, which is addressed at 10.2.0.1, and if it is a /24, then your dhcp.conf must point to addresses in 10.2.0.0/24. Here are the changes I would make, if I've understood your addressing.
Code:
option domain-name "my.domain";
option domain-name-servers 4.4.4.4;
subnet 10.2.0.0 netmask 255.255.255.0 {
option routers 10.2.0.1
range 10.2.0.32 10.2.0.127;
}
