equinux VPN Tracker 6.4.6 - Manual (Page 61)

What should I do when I get an alert that other software is already
using the standard VPN network ports?
If you do not need to use the other software (e.g. another VPN client or
Back to My Mac), simply quit VPN Tracker, disable the other software, and
then open VPN Tracker again.
If you would like to use the other software together with VPN Tracker, click
continue and see if your VPN connection continues to work. If it does, you
can select “Always Use Other Ports” the next time you see this alert.
If you ever want to revert back to the standard VPN network ports, open
Preferences and check both “Use fixed port for IKE” and “Use fixed port for
NAT-Traversal”, and make sure they are set to 500 and 4500, respectively
VPN Status
Use this setting to enable and disable the status menu in the menu bar of
your Mac.
Testing VPN Availability
VPN Tracker automatically tests if VPN is available over your current Internet
connection before attempting to connect to your VPN. Testing occurs only
once for any given Internet connection – for example, the first time you at-
tempt to connect from a hotel’s Internet access, VPN Tracker will test the
Internet connection. When returning to that hotel a few months later, VPN
Tracker will usually not have to test again.
Testing your Internet connection enables VPN Tracker to adjust its NAT-
Traversal settings according to what your current Internet connection sup-
ports. For more information about NAT-Traversal and how VPN Tracker is test-
ing an Internet connection, see
→ VPN and Network Address Translation (NAT)
Disabling VPN Availability Testing
It is highly recommended to let VPN Tracker test unknown Internet connec-
tions for their VPN availability: If VPN Tracker knows what NAT-Traversal
mechanisms are supported by your current Internet connection, VPN Tracker
will be able to avoid many common connectivity issues automatically.
However, if you are using VPN Tracker to secure access to internal networks
from another internal network (e.g. securing a corporate wireless network), it
may be necessary to disable testing (entirely or just when connected to this
particular network).
For all Internet connections:
‣ Open Preferences
‣ Uncheck “Test VPN Capabilities of Unknown Internet Connections”
For the current Internet connection:
‣ Open the VPN Availability Test (Tools > VPN Availability Test)
‣ Click “More Details”
‣ Check “Ignore test result”
You can also choose to skip the test while the test is in progress.
To reset all skipped Internet connections and start testing again, click the but-
ton “Forget Skipped Locations” in Preferences.
