50% isn't bad. I would think filling up queues or something similar is
a likely cause.
To answer your questions you shouldn't have to do anything other than
move the queues, etc. to the inside router. Give it an address out of a
/30 and the edge router the other address from the /30 and just let them
route. No NAT needed on the inside unit.
You might also consider moving the DNS to a real DNS server. You may be
running low on memory because of he DNS cache.
If you need help with the router configurations, hit me off-list.

Hello.
I'm trying to improve performance on our network, I have a RB3011 with
about 370 clients doing queue, balancing two 100M lines, NAT, DNS,
among other things. At around 8pm to 10:30pm I've had customer
complaining about "slow internet". CPU on this device has gone up to a
little over 50% and I think is time to do something before is too late.
I have another RB3011 which I would like to use to help out the other.
I want to leave in the current unit balancing the internet and have
the new one do queue, firewall, and other stuff.
Now, I don't want to double nat. How can I do it? or can you please
guide me to where I can have an idea on how to do it.
This is basically what I'm trying to accomplish:
WAN ---> RB3011 (172.16.0.1, balancer) ----> RB3011 (queue and stuff)
----> LAN (172.16.0.0/16 <http://172.16.0.0/16>)
Thanks in advanced for your time and help.
