My friend recently upgraded his Router/Modem combo on DR to a Vigor 2750n (on my recommendation) as is now unable to VPN to our works VPN (Draytek 2820).

Before he was on a TPLink Router, and using the VPN PPTP in Mac OSX could connect to the 2820 and everything worked fine, now on the Vigor 2750, it connects and works for about 4 seconds then pings just return

Code:

ping: sendto: No buffer space available

I'm also on a Draytek (2850) and have no issues connecting my Mac or PC's via PPTP to the 2820, and no one else has any issues, so this has to be something to do with the Vigor 2750! Its on the latest firmware. Can anyone offer any advise?

Thanks.
