For example, if your remote network is 192.168.13.0/24, do not use an address starting with 192.168.13. Please use a local address that is outside all remote networks. Using a local address in VPN Tracker (Basic > Local Address) that is part of the remote network is not possible with most VPN gateways. Is the local address in VPN Tracker part of the remote network? Is the IP address you are connecting to really part of the remote network?įor example, if your remote network is 192.168.13.0/24, you should be able to connect to IPs starting with 192.168.13.x, but connections to IPs starting with 192.168.14.x will not work as they are outside the address range of traffic tunneled through the VPN.ģ. Note that using Bonjour or NETBIOS hostnames is generally not possible over VPN.Ģ. Please make sure DNS is enabled for the VPN connection and correctly configured.

If that works, the problem has to do with DNS resolution. If you are using a host name, please try once using its IP address instead. Are you trying to connect to the destination device using a host name? The destination device can be anything from a normal computer, to a server, to a network printer.ġ. In this FAQ we will be using destination device as a generic term for the device you are trying to connect to. This FAQ will help you to find out what is causing the problem in your specific situation. So, this all has to fall back on IT for some reason.There are a number of possible causes for such a behavior. Because apparently he doesn't trust the supervisors of the staff that are working from home. The reason I asked the question to begin with is because my boss asked me to have users booted off the VPN after 15 minutes of inactivity, so we can see how often they are getting disconnected/logging back in so he can determine if people are actually working from home. Okay, so now that I know what SonicWall means by "Inactive" (IE: broken link), meaning my immediate supervisor (.the CFO.) wants me to do the impossible once again. I wonder if it's more 'broken link' detection than actual 'idle time'What happens if you turn off the wi-fi on your machine at home?įuricle - That was it! I just killed the wifi, and about a minute later the 'Inactivity Time' was showing 1 minute. There has to be a way to go about this though.I mean, why else would they have the 'Inactivity Timeout' option? I find it hard to believe there would ever be a way to detect the idle time for a VPN Client, as there is always something happening behind the scenes of any networked device. I reconnected to the SSLVPN and after 5 minutes the "Inactivity Time" still shows 0 minutes and the packets sent/received is continually incrementing, meaning there is data being sent behind the scenes that is preventing an idle time from accumulating. For lack of anything else to try, I did disable NAT Traversal to see what happens.unfortunately, the results are the same. I think you are on the right track about a keepalive packet being sent over the VPN, but I thought that the NAT Traversal settings you mentioned are for Site-to-Site based connections. The “keepalive” is silently discarded by the IPSec peer. Therefore, to preserve a dynamic NAT binding for the life of an IPSec session, a 1-byte UDP is designated as a “NAT Traversal keepalive” and acts as a “heartbeat” sent by the VPN device behind the NAT or NAPT device. IPSec VPNs protect traffic exchanged between authenticated endpoints, but authenticated endpoints cannot be dynamically re-mapped mid-session for NAT traversal to work. There will be some kind of 'keepalive' packet being sent between the client and the host, not sure where to look to configure it but can guarantee that's the problem!Įnable NAT Traversal : Select this setting if a NAT device is located between your VPN endpoints.
