Hi, I have a VPN running which looks like a hub-and-spoke configuration. For the remainder of the discussion, the spokes are OpenBSD 4.4. Since I've upgraded the hub to 4.5, a connection to one of the spoke starts to fail. After running for well over a week, the connection was not automatically renegotiated. I first reset the spoke, but to no avail. I could see the connection going just up to INFO_PROT encrypted, and then the hub stopped responding to that spoke. Things only returned to normal after I said "echo R > /var/run/isakmpd.fifo" on the hub.
How do I debug this, please? TIA! Kind regards, --Toni++
