When running VPN discovery from VPN manager on the OneClick console, we are given the option of adding text, to filter the networks we want to include or exclude in the discovery. This filter instructs us to "Enter Provider Name - Wildcards (*) Accepted"
However wildcards will be used, even if we do not include them so we have no option to exclude networks of similar names.
e.g. if we have networks called "Network", "Network1", "Network2" and "Office" and we put the filter "Network", (with no wildcard) then all the networks that begin with "Network" will be discovered.
