I have a RB 153 at home, with 2 mini PCI cards in. Internet is used on one card and the other is to connect to a network with some friends.
My internet is using PPPoE, and has masquerading. The ip range is 172.21.x.x
I have setup a firewall rule to keep the internet off the other network. My question is, in my routes it is setup to forward any traffic in the 172 range to the network with my friends and 0.0.0.0 to internet. sureley I do not need the firewall rule if the routing is setup in the way it is?
hope this makes sense.
Thanks in advance.
