Please post on the Gumtree site geographically closest to you. Ads will only be accepted that are geographically specific and locally relevant. This local community approach is what Gumtree is all about. If you are local and you still get this message, then it means your local Internet Service Provider (ISP) is using a foreign IP. In this situation, please contact your ISP for more information on how to change this and make your IP local to Ireland.
If you would like further help please let us know by clicking on "Contact Gumtree" located bottom of help pages and we will take a look at your situation.
