Jiglu has a blacklist of IP addresses from which it is not possible to add a source, such as a feed or spider, or to obtain details of links included in contributions. This prevents users, who might be from outside the organisation, from using these features to get information about internal servers. By default the private address ranges and the local loopback range are blocked.
However, sometimes you might want to use information from a local server and know that you have users that are suitably trustworthy. In this case you can modify the blacklist to allow access. To do this go to System settings, choose the Content lookup category and then for the Connection blacklist setting modify the address ranges appropriately.
