Hi all. I have swapped out a couple of 2820s on various sites and upgraded to a 2830. Exact same config (built from scratch). Nothing else changed. I am seeing way more drops on the IPSec tunnels with the 2830's compared to the 2820's. Canprove this by putting the 2820 back in & IPSecs are far more robust. 2830 running latest firmware so can't think what it is other than the new model.
