I need to know how to have the firewall block web addresses with IP addresses in them on a Vigor 2830n.
e.g. 'http://123.123.123.123'' needs blocking but 'http://thingy.com' is allowed.

Unfortunately I need to also allow a couple of exceptions or a whitelist too.

My search so far has only found a couple of sales adverts that say that the Vigor can do it but with no further info.

Any help appreciated
