You are right, I assumed that 192.168.64.1 is his gateway and stratum serve=
r. If it is,
then what I posted previously should work, if it is not then he should to S=
NAT also.

iptables -t nat -A PREROUTING -i eth1 -s $LAN_SUBNET -p udp --dport 123 -j =
DNAT --to-destination 192.168.64.1:124
iptables -t nat -A POSTROUTING -o eth1 -p udp --dport 123 -j SNAT --to-sour=
ce $GW_LAN_IP

Right? :)
