Hi
I currently have a RB433@300mhz which is configured as the 3 LAN Interfaces in a Bond, Bond interface split into 15 vlans. On one VLAN there is a PPPoE client connecting to a 40mbit service, and another is to a 20mbit service (this is not PPPoE however). The 20mbit service is only used for specific servers. The Firewall NAT rules are simple Masquerades and the traffic is routed down the 20mbit using an ip route rule (src ip) to a specific routing table.
I'm seeing that if I try to push much more than 34 down the PPPoE and 15 down the other interface the RB will reboot randomly after it hits 80% cpu or there abouts.
There are not a crazy number of FW rules (6 filters, 1 mangle (MSS Fixing) and 5 NATs), and there are (currently) no Queues being used.
I'm presuming that I'm pushing the rb433 to the limit, however I'm not sure on what would be a good idea to replace this with. The 433GL seems to be able to handle about 2x the throughput according to the benchmarks, however I'm obviously anxious that should my 40mbit server be upgrade to 80 mbit (which it is due to be soon) then I will be potentially pushing the 433GL to its limit.
What would peoples recommendations for this, also taking into account the potential for adding in some queues in the future
