No, you are wrong.
Permitting access to the router's IP doesn't grant you access to Internet.
That rule in particular only lets access to the router IP, probably for configuration access (the rule name says everthing, in fact).
Unless you have a proxy in the router and you need to access internet through it, that rule is just dumb and the way you pretend (the guy of dslreports, actually).
I use Kerio 2.1.5 myself and I have access blocked for the router IP except one app as a measure for XSS attacks and... you know what? Here I am!!!
You need to understand that when you connect, let's say to this forum, you aren't requesting access to the router and then the router to the forum IP out there.
Windows applications directly calls the forum IP through the windows socks (or whatever library is used in Win7). When this happens, windows founds that the IP can't be access directly (by its network) and there will try to use, in this case, a gateway (do you know what is a gateway?), in this case 192.168.1.1 and the router will route (there is where the name comes) accordingly the IP packets to where is needed, but, even the router, doesn't know where to route, it will send the packet to its ISP gateway too, and this will route to another, and another, and another, until the forum is reached.
Actually, Windows and the forum will talk themshelves but after different routes.
I will tell this simplier. Do a tracert to kmeleon.sourceforge.net and look if the router IP (or other router acting as gateway) appears somewhere.
You'll find that there is no where.
This was a dumb test also, because it will tell just the routing, but will show you that routers, actually gateways, won't be shown because they aren't involved at all in the connection. Just they give access from one network to another. And even if you block any IP in the route, you will still have access to the kmeleon forum because what is important is the point to point connection, not the routers and gateways.
After this long explanation (and brief), if you find a replacement for Kerio 2.1.5 and Windows 7, tell, please.
I had a look to PC Tools Firewall in the past, because it looks simplier, but there is nothing like the old Kerio
and that is the reason I don't recommend it to you or anyone.
