Hello,

in your reverse zone:

$ORIGIN .
$TTL    2147483647
@       IN SOA  ns2.starka.st. hostmaster.starka.st. (
         2025062711 ; serial, todays date + todays serial
         14400      ; refresh (3 hours)
         3600       ; retry (1 hour)
         2419200    ; expire (1 week)
         3600 )     ; minimum (1 day)
         NS      ns2.starka.st.
$ORIGIN 0.168.192.in-addr.arpa.
#100	PTR     host1.example.lan.
224	PTR	tMbERG_tMbERG_.224.starka.st.

I *think* the origin is wrong?
My guess is that this should be

$ORIGIN 0.168.192.in-addr.arpa.

Hope that helps.

It is very helpful to include *what* exactly you have tried, and what 
the resulting errors were ;)

Best,
