Can anyone recommend the best current model Routerboard for use on xDSL when running an IPSec tunnel between 2 devices?
I have read some devices are better as the hardware can accelerate encryption performance rather than relying so heavily on CPU?
Bear in mind that I only use 2 x interfaces on both devices - one interface goes to xDSL modem, the other to a HP managed switch.
Currently running a RB750 on ADSL2+ Annex M and RB750GL on VDSL2 (80/20).
My RB750 CPU has put itself down to 250MHz and is maxed out solid at 100% with around 80% showing on profile as in use for encryption.
RB750GL by contrast when transmitting the traffic the above is receiving is still running OK at 400MHz with a CPU load around 60%, with around 50% encryption.
RAM usage on RB750 is high but using only about 50% of the 64MB on the GL.
