Hi,
how can i forward multiple external ports (eg. 20001-29999) to multiple internal ports with translation (eg. 1-9999 => means minus 20000)?
Translation of one port i got done; multiple to one also.
Thanks vor your help.

My Try
Hi…
Are you trying to rewrite the external opened port to internal ports, changing the start-end of each side?
Correct?
yes
WAN 20080 => LAN 80
WAN 20443 => LAN 443
WAN 25901 => LAN 5901
Hi…
Test here (RUT240)
- WAN (8080 > 8888) works with " no rewrite " to LAN
For rewrite WAN TO LAN
Only works in my device, building rule for each data traffic between wan and lan
Sample…
With no rewrite it works for me too, but that dont help.
I can’t make a rule for every port, this would be too much rules.
What means Port range in the help (screenshot)? How do i have to use it? Is there an example with this parameter?
In other router/firewalls this should go like my example. Could this be a bug?
I use it… that external ports will be the same as internal ports…
Teltonika build this, respecting external and internal ports for pool of ports range. This is very needed by pure FTP use. (PORT MODE / PASSIVE MODE)
I take a quick look, around the forum… I don’t find anything about. ( Maybe I am not a luck guy )
I don’t know… Maybe anoher network vendor, can do this.
I don’t believe this is a BUG… My RUT is running a old RUTOS (openwrt) version and yours RUT is running a up to date version. Both did the same.
Maybe should be a request for a feature to be add in the device??
But why do i should use this? I can select “no rewrite”, this is much easier. What is the difference between
5000-5500 => no rewrite
and
5000-5000 => 5000-5500
?
Is someone from Teltonika reading this forum or where can i place my feature request?
Thanks for your help!
When a packet arrive at WAN 5001 wil be the same 5001 at lan of the local internal network device, behind firewall. ( no rewrite )
BUT
When at WAN arrive tcp_50001 and at LAN should be TCP_5001, using rewrite, the device understand the rule.
Teltonika need to have somekind of pool rule, to do an association for a rewrite pool of ports, allowing us to configure rules for this.
Hello @IWS,
Could you please confirm if your topic has been resolved, or do you still need any assistance with this?
Best regards,
