Let's say I have a setup like this:ip.tun0:0 a --> b ip.tun0:1 a --> c ip.tun0:2 a --> d Internally, each one corresponds to an ipif_t structure, which has no packet or byte counters! Is there a practical, programmatic way to see if traffic has passed over a "virtual" interface? The problem I'm trying to solve, BTW, is to remove virtual interfaces that have no traffic on them after a certain period. If the current answer is "no", would future projects already in the pipeline (i.e. Clearview) change this answer?
One way that I can think of to do this is to use IPFilter's (:-) count rules with filters that somehow distinguish :0 traffic from :1 traffic. You can reset the counters back to 0 with a cronjob and look for inactivity at the same time. Is that within the scope of possibility for you?
