Thank you, it will surely help, Fulvio.
However, it should be better to “reorder” all these numbers (so that 05 80 95 become 01 02 03) every time some insertion in deleted, in order to maintain the list over the years (in some time in the future we will reach any limit, as the numbers are everytime higher and higher…). And even better should be to reorder them in alphabetic order (based i.e. on destination IP), to have the list in order, or even better to add the “Name” to every insertion and then order by this name — now, when there are more then 70 lines (created over the years thus with no specific order), it is something confusing.
The PortForwarding feature is likely the most used part of Zeroshell in many development offices where the requests are changing rapidly.
