And another question, should I go for RB450G or for RB750G?
The 450G is actually better than the 750G
Why is it better? It has more RAM, but in my case, do I need it? (I want 100mbps NAT and 2000+ TCP simultaneous connections for 3-4 PCs)
Do I need to hold the full internet route table?
What do you mean by that?
Usually there is 1 (in your case 2) routes for internet access.
I did't know what's with that whole internet table. So for home NAT it doesn't matter.
But, to satisfy my curiosity, when would someone need to hold the full internet table?
I think the 450G will do the job.
I tried a 750 at 50 Mbit/s with BitTorrent and though the load was over 90% it did work fine.
A 450G should easily get this far.
So the 450G will NAT at 100mbps + many many TCP connections?
Keep in mind that without a router, uTorrent downloads at 12mb/s if enough seeds.
How about the 750G? (It's 20% cheaper and it has a case)
Is there any scenario in which I'd need the extra RAM?
And another question, should I go for RB450G or for RB750G?
Do I need the extra RAM?
Do I need to hold the full internet route table?
Personally I'd go with the RB450G. What do you mean by holding the full internet route table? Are you doing BGP?
No, I'm not. When is BGP used? Which are its advantages?
I've checked some articles on wikipedia, but I did not understand much besides the fact that it's very important and it is used by most ISPs.
Assuming 80% utilization - 80Mbps on each line and average packet size of 1000 you have a line capacity for 40000pps. RB450G and RB750G and any of PPC boards will do.
As far as security goes RouterOS offers stateful firewall and little else. If you're serious about security you'll need to think about IDS/IPS.
rmichael, do I need these for a home network?
What would you suggest?
Man, it would have been much easier to build a PC router, but I can't afford it, and it consumes a lot more energy.
Also, most commercial routers that are in the same price league with RB450G/750G can't handle more than 2-300 TCP connections, or 100mbps NAT.
