Telstra Gateway Pro (Netgear model number v7610) and Sophos Client Connect VPN

Question

Hi all, 
 One user has a Telstra Gateway Pro Modem and he is not able to use the client connect VPN. 
 
 I have opened ports 500 ad 4500 for UDP on the modem, but i still get the error. 
 I run netstat to see all the ports and 500 and 4500 are open for UDP

Thank you, 
 
 Johana

Yeah, we had the same problem and have three of these devices at different locations. Telstra are about as helpful as the magpie on my lawn... and not quite as smart. 
 After some pain, trial and error we found that you have to add a Port Trigger to the V7610 for UDP port 500. 
 Login to the Router and go to ADVANCED tab Click on Advanced Setup in the side bar Click on Port Forwarding / Port Triggering Please select the service type Select Port Triggering (radio button) Click on " + Add Service " button Enter the new Service: Port Triggering - Services 
 Service Name = VPN Service Service User = Any Service Type = UDP Triggering Port = 500 Inbound Connection = UDP Starting Port = 50000 End Port = 50100 Click the green " Apply > " button OK, now try to connect using Sophos Connect VPN, YAY! 
 Hope this helps
