could be...I didn't think so. Testing was easy enough, in fact, that's
where I started...
#!/bin/sh
#
echo 1 > /proc/sys/net/ipv4/ip_forward
modprobe iptable_nat
iptables -F
iptables -t nat -F
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -A PREROUTING -p tcp -d 192.168.3.8 --dport 445 \
-j REDIRECT --to-ports 1445
iptables -t nat -A PREROUTING -p tcp -d 192.168.3.8 --dport 139 \
-j REDIRECT --to-ports 1139
iptables -t nat -A PREROUTING -p udp -d 192.168.3.8 --dport 137 \
-j REDIRECT --to-ports 1137
iptables -t nat -A PREROUTING -p udp -d 192.168.3.8 --dport 138 \
-j REDIRECT --to-ports 1138
