networking – Nat routing from static IP trow VPN not working

I try to rout traffic coming from 185.220.xxx.xxx:53 on interface ppp0 to 192.168.1.2:53 on interface ens3. I think something wrong with my settings.

# NAT table rules
*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
-F
# Port Forwardings
-A PREROUTING -i ppp0 -p udp -d 185.220.xxx.xxx --dport 53 -j DNAT --to-destination 192.168.1.2:53

# Forward traffic through eth0 - Change to match you out-interface
-A POSTROUTING -s 192.168.1.2 -o ppp0 -j MASQUERADE

# don't delete the 'COMMIT' line or these nat table rules won't
# be processed
COMMIT
