Hi, I just discovered that pfsync needs the sync device to be numbered, even if I simply try to use the multicast address and don't specify a syncpeer. Not numbering it, but simply pulling it up, yielded (eg.)
# ifconfig pfsync0 syncdev ste3 ifconfig: SIOCSETPFSYNC: No buffer space available In some emails regarding this issue, but pertaining to older versions of OpenBSD, it was suggested that an unnumbered interface would do, and I think that it should if one uses the multicast addresses, so I'd suggest that this could be mentioned in the documentation (unless I hit a bug, of course). This is OpenBSD 4.4-stable. Kind regards, --Toni++
