as RDP exposed directly to the outside world is not recommended
Sure, which is why one would run RDP only via a VPN.
If one cannot get the VPN up (e.g. lack of password) then one will not reach the internal network on which the RDP server is sitting, surely?
Are you saying there is an issue there, e.g. the Ipad is prone to connecting without the VPN being up?
That is certainly a problem in a normal "travelling laptop" scenario where you open a VPN to your office (e.g. to check your POP email securely) but if the VPN connection drops, the email client will happily carry on making the access without the VPN
With a browser one can force VPN-only operation.
The newer Draytek routers do SSL-VPN if you require (alongside PPTP/IPSec)
I am trying to get rid of Drayteks. We have some 2900s here and they work fine but VPN stuff is very buggy. And the seg.co.uk support forums suggest that the new Drayteks are little better.
but it's not great from a usage POV.
Are you able to elaborate?
