Yes, the 450 and 750 lines would work very well for you in what you are looking to do. I personally prefer the 450’s because of the COMM port. That way if you mess something up, you can always get into it again. The 450G also has more RAM than the 750G, and that is always a plus.
You can look at doing policy based routing or load balancing if you want to utilize both fiber and cable connections, or you can just have simple failover going. Since you want one “house” to always use the cable, then look at policy based routing for them and expand from there. Since it sounds like you want to keep each house separate then assign a different subnet and use each interface as it’s own routed interface. Then you can use the firewall filter to keep connections between the subnets down to just what you want to allow.
For the tunnel connection between your sister and your house, that’s fairly easy to do. You’ll just need to establish the tunnel with one of the supported protocols and then set up a route for your local subnet on her router so the router knows how to reach your private subnets. Since it would just be a route to your private subnet then the more general default route would catch everything else making her go out of the cable connection.
computers can see all each other its not a problem, but i just want my sister to use her local net connection for surfing and so on so it does not congest my connection
and the third house can see all comps but only to have 16mbit connection that i will use for fail over
tnx again for all info so now i can buy this and start learning i have now PFSense but only for my connection and no failover
i just made quick diagramm and wanted to post it… but now i dont have to post it i’ll have to start reading
and… i’m planing on buying 750 not 750g for my sister…
… one more question…
if one of my friends buys also RB … will my future RB450G then be able to handle lets say 4-5 Ethernet over IP Connections? i have 7 Desktops, 4 laptops and few phones going to internet over my future RB450G
Yes the 450G should be able to handle that fine. We have standard 450’s running hotels that have anywhere from 45 to 150 unique users in a 24 hours period just fine. It just mostly comes down to how efficient your firewall rules are, your queue set up if you have any, and what other services you are running on top of the router. As long as the CPU stays bellow 100% you are good to go mostly.
Yes the RB does come with a DHCP client and can do PPPoE if needed.
You can modify the scripts to fit your needs, like updating to a DDNS service, or what we do when we need to use DHCP is have the routerboard e-mail us the IP on startup or when it changes.
