как настроить прямую и обратную зону для работы с такими сетями? »

зоны должны прописываться независимо от сетей. Главное чтобы клиент мог записать тута, и ДНС разрешил туда запись из таких-то сетей.
но я вижу у вас доверенные сети - только /24:

Код:

acl "trusted" {
	127.0.0.1;
	localhost;
	192.168.11.0/24;
	192.168.12.0/24;
	192.168.13.0/24;
	};

настройки изменил:

named

Код:

acl "trusted" {
	127.0.0.1;
	localhost;
	192.168.11.0/24;
	192.168.12.0/24;
	192.168.13.96/27;
	};
...

listen-on { 127.0.0.1; 192.168.11.254; 192.168.12.254; 192.168.13.126; };

...

zone "96/27.13.168.192.in-addr.arpa" IN {
        type master;
        file "/var/named/13.168.192.in-addr.arpa";
        allow-update { key rndckey; };
        notify no;
};

dhcp

Код:

zone 96/27.13.168.192.IN-ADDR.ARPA. {
    primary 127.0.0.1;
    key rndckey;
}

... 

subnet 192.168.13.96 netmask 255.255.255.224 {

    option routers            192.168.13.126;
    option subnet-mask       255.255.255.224;

    option domain-name        "samba.linux";
    option domain-name-servers    server;

    option time-offset        -18000;

    range dynamic-bootp 192.168.13.97 192.168.13.125;
    default-lease-time 21600;
    max-lease-time 43200;

}
