[Samba] Forwarding ports on SG20 with Redhat Linux

[Steve Smith]

I have a Toshiba Magnia SG20 network appliance server. It runs Redhat Linux 7.3 and Samba and has a built-in router. See http://www.linuxdevices.com/articles/AT7915816249.html . The web interface does not provide for forwarding ports. Does anyone know how I can forward ports on this device?  Btw- I can Telnet and SU to root.

Thank you,
Steve Smith
