Hi, Im wanting to use the back to my mac feature but its saying my router needs to supports NAT Port Mapping Protocol (NAT-PMP) or Universal Plug and Play (UPnP)

Can someone tell me how I can turn this on?! Im guessing it can handle it but having no luck finding it

Cheers Guys

Depends which router but for most of the recent ones, its under the Applications menu then UPNP, the first tickbox is all you need to enable for UPNP to work

Good luck with that. I'm trying to get BTMM working with my 2820 but it simply will not. Neither will 3rd party services that are similar, like ShareTool. I've asked support just now and am waiting for a response. There are loads of posts all over the internet saying that Draytek routers simply don't support it

Yeah having a nightmare with it....Let me know if you have any luck! I too will post if I have any joy

BTMM uses IPSec, disable the IPSec server on the router and BTMM should work if UPNP is enabled. That's something Apple don't include in the setup instructions too much but if you use BTMM, it sets your mac up as an IPSec client / server so needs the router's IPSec server out of the way to operate.
