Hi David,
Thanks again for your reply.
to change the router(s) is not an option.
the one that's the default gateway is a ADSL modem maintained by the provider.
The other one is a simple Hotbrix firewall without features like that.
I would realy appreciate that the SME server can do this and we can create a template about it.
Perhaps i have to study on the templating system to be sure how i can create this.
Thanks a lot.
