Using top(1), which is my indicator for the problem, is sending normal output. The router has igb0 as tun0 and is spanning the network via vlans via igb1. Connecting to a host inside my network and havinf heavy net I/O doesn't reveal any problems so far. Direct access to the APU from outside is prohobited. When loggin into a host inside my private net from my department and then from there toward the router (APU) as a wheel-grouped user also doesn't reveal problems using top - but I have users restricted to see only there own ID and also there groups are limited via some bsd_see_others... sysctls. It gets funny when sudo su -'ing to root on the APU and then using top. Immediately the net traffic freezes forever! Kind regrads oh
