lol.... stand by... looking up your router now...
This it?:
http://www.dynalink.com.au/products/specs/rta300_specs.htmAre you connected to it by USB or ethernet?
Do you have access to its configuration?
Do you have a copy of the user manual referred to in the install guide linked below?
looks like the router will support
"virtual servers" Ack - port forwarding they mean, and it looks like it will not take a port range but only single values... SFC requires 2300-2400 and 47624, so unless it can take 101 single "virtual server" entries or will accept a range then you may be out of luck... though Dxport is potentially a solution for that.
rta3xx support pageRTA300 install guideCheck the "configuration-security-firewall" page on your router...
perhaps there is a DMZ function?
hmmm, can't find a link on their page for the RTA300 user manual but there is a link for the RTA230...
perhaps their support staff can tell you why the manual is unavailable (if you don't have it from the original packaging):
