RB1000 overloaded? Solution?

Hello,

I have one RB1000 as Gateway. When there is usage about 50/20 Mbps CPU is at 70-85%…
On this Gateway is also enabled firewall, mangle, etc…

I’m connected like this…

FIBER OPTIC > (ether1) - (ether2) < CLIENTS

And my next idea was to buy two more RB1000 and put like this

FIBER OPTIC > (ether1) RB#1 (ether2) RB#2 + (ether3) RB#3

I would put my one IP class /22 (about half users) on RB#2 and another IP class /22 (and second half users) on RB#3…

And is it better for RB#1 to be just transparent bridge for FIBER OPTIC or also router, firewall? Or it’s better have router and firewall on each?

Thank You in advance! I hope You understand me…

why three RB’s i guess 2 would do if you need to have half the subscribers on one rb and the other half on the other. Just request your ISP for 2 public IP’s and have one IP on either

I assume you are managing your clients with some kind of dynamic AAA (dhcp or pppoe).
i’d configure the systems like this:

PPPoE/DHCP parallel managed with RADIUS
                    | 
               / >> RB#2 \
FIBER >> RB#1 |           | SwitchGbit > CLIENTS
           |   \ >> RB#3 /
           |
      QoS Mangle and Firewall

The IP assignment can be done dynamically by RADIUS while the load balancing will be done automatically between the two RB (the less heavy loaded will get the client requests)
I dunno all your specific requirements but maybe a consultant will give you the best ideas for your ISP

@Medianet: That’s what I’ve planned, but I’ll ask my ISP if they are able to give me 2 gateway IPs on FIBER OPTIC and try idea from @gmidia
