Just got hold of a 2760n, connected to Sky ADSL just fine.
I do think of myself as being a bit tech savvy, but the myriad menu options have got me stumped so far.

I just want to enable port forwarding on TCP 3389 for me to remote desktop to my PC from work. All the previous routers have had an intuitive menu to sort this.
On the 2760n do I do it from the NAT menu, I'm unsure? A quick step by step guide would be a great help.

Thanks

sorry i may not be much help to your issue because never used this option but yes you need use under NAT for port forward
You can also load the latest firmware released today & has vectoring & also can use Lan 4 as an incoming second wan if ever you will put back your provider isp modem & many other fixes

if you do update then use of the *rst* file extension is recommended to avoid previous conflicts/bugs and setup manually from the begin (not use of backup file)
