I need to know the 450G throughput, and Product specifications says:
(http://routerboard.com/RB450G)

RB450G @680MHz (2 port test) -------------64 byte frames------512 byte frames--------1518 byte frames
IP Firewall ---- Conntrack ------ Mode ------Mbps -- Fps--------Mbps---Fps-------------Mbps-----Fps
off ------------ off ------------ Bridging----76.9 ---150200-----595.15--145300---------1220.47---100500
on ------------ off ------------ Routing----52.38 ---102300----396.08---96700----------1035.88---85300
on ------------ off ------------ Bridging----44.95 ---87800-----353.08---86200----------947.23---78000
on ------------ on ------------ Routing----39.68 ---77500-----300.24----73300---------823.36---67800
on ------------ on ------------ Bridging----29.9 ----58400-----232.24----56700---------660.63---54400

But in practice, in normal use of http internet traffic, what is the throughput? What is the frame size?

I just need to know if the 450G can handle 2 Wan of 25Mb each (50Mb total), with IP Connection Firewall and conntrack in normal conditions (with a mangle, etc. optimized)

Thank you very much

I'm interested in this as well so look forward to other posts. Sorry I can't be of more help.

It´s underpowered for 50Mbps + policy routing.

My experience of RB4xx versions was with RB493AH doing load-balancing with pcc and 4 adsl.

With RB493AH in production my max bandwidth was 32Mb/s.

Exchanged to a RB1100AH and now i get more than 41Mb/s.

Configuration is typicall, nat + mangle for pcc and some filter rules, nothing more.

If no policy routing is needed, it can do much more.

I have a couple of them running on docsis3 modem with 120Mb/6Mb and it does this very easily with a light config.
