@dreamslacker:
Try Ebay. You are probably stuck on getting a Single GBe NIC and having to use VLANs with an appropriate switch.
The RB250GS is a good choice for the switch. Check in on Lowyat forums to find out more details on the configuration since a lot of TM UniFi users use it for connecting their own routers along with the IPTV STB.
For the NIC, I'd recommend getting the Intel PT Gigabit adapter.
True indeed, maybe i rather get this RB250GS switch and run it
ADSL-> Pfsense -> RB250GS -> Workstations/ laptop , but how about connecting through wifi such as iphone /Acryan ?
