I have a Watchguard SOHO 6, this is connected to the lan switch and to a Zyxel 623 Dsl Modem/Router. All internet traffic must flow though the SOHO 6 first and then to the Zyxel Dsl Modem/Router.
Everything works fine from the client machines and all can access the server and the internet. The problem is when I set the SOHO 6 firewall setting to deny either incoming or outgoing connections nothing happens and the ports remain in the original state.
(example: I block port 80 on the SOHO 6 but... Port 80 is still open and internet access is still available)
