My openbsd router/firewall (currently 3.9 but have had previous versions with the same issue) will sync to external servers and also to internal linux servers running openntpd. However, if I attempt to use the openbsd box as the internal time server (listening on the internal interface), and point openntpd on the linux systems to the openbsd box the sync fails. IOW openntpd works with linux as the server, but not with openbsd as the server.

And how can I fix it? Thanks. Chris
