Rather than stop this, why not implement something like Floodgate to give
this traffic the lowest priority ?
You should be able to get a 30day eval license to try this out from your
reseller.
Blocking yahoo and hotmail will annoy a lot of users - most people will use
these services daily.

Hi!!!

I would like to know how may I deny the access to webmail sites in
checkpoint firewall-1?
We use NAT, and about of 70% of the traffic across the firewall is of people
downloading files from
their external e-mails (like hotmail, yahoo...). This is a big problem for
us.
I have a little idea of how it can be done, some people said that is using
URI (??), but I'm not sure.
Does anyone know how to do it??
Thank you.

Marinho Paiva Duarte
