Portforwarding and UVNC single click

[rischfre]

Hi

for years i m using the Single Click software and working fine.
But now i would like to change the logic, instead that the the SC program point to each remote computer i would like to do the following thing :
each port of a server represent a computer (ex. : 192.168.1.2:10107 --> 192.168.1.107), so the point is redirecting what receive the server to the relevant computer.
my server is a Linux server, so I tried follwing command line :
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 10107 -j DNAT --to-destination 192.168.1.107:5500

but i receive following error :
Connection failed - Error reading Protocol Version

Did i missed something?

Do you have the iptables FORWARD command configured as well?
