Hi,
I cannot bid for $50, the minimum is this, you need to modify the budget first I think.
Can forward your port, if you can install iptables it will be easier, if not you need a C/C++ compiler on the machine so we can compile some program to manually forward the port, like a proxy.
Will need access to the machine and do the job, after will tell you how I fixed.
Any doubts just chat.
When you change it will bid for $50 on this.
Thanks
