Probably not all of them anymore. The 66.29.58 addresses, while still allocated to us aren't really used anymore, so they could probably go. The rest are needed. > If these are required for IPSec, can you give us an idea > of the IPSec SPD entries being used without leaking sensitive > information to the public? You know.. IPSec is probably the only thing I'm *not* using, though you probably noticed I was at least thinking about it at one point :).. It might not be a bad idea for me to remove it from the kernel though and see what happens.. > I think we need to also have a look at the routing tables and > output of `sysctl net.inet kern.ipc` might be useful. > Also give us the list of loaded modules (kldstat). Sure.. The routing table is managed mainly by quagga (outside of the default route) bgpd.
