If it is UK only you can restrict to just UK IP addresses. Or maybe you can just allow the EU ..I do that on our VPN and FTP because I know it is only our employees and a handful of vendors that will connect. So I block the whole world except the US ..

We have selectively been blocking the offending public addresses. However as you can imagine, this exclusion list will only continue to grow and become unmanageable. As of yet we do not have any ACLs in place that identify the our/customer traffic from non-customer traffic which is pretty much the root cause of this issue. It is like this for a couple of reasons: 1. Some of our customer users have the ability to connect to these servers from their homes (i.e. access out with their parent company LAN) where their broadband connection would potentially have a dynamic IP address. 2. From our own perspective, if we were to lock down access to these servers by IP addresses, then we ourselves become at risk (in terms of not being able to provide customer support, especially since we have some pretty rigid SLAs in place). If the VPN to our Data Centre goes down, we would have to send people home to continue working. Therefore we have the same issue(s) as outlined in point 1. Above. Therefore I would be interested to know how other people are handling the same/similar situations and any recommendations you may have?
