My Multinet compatible implementation under RSX might
have some issues
communicating with VMS nodes, but in general it seems to be working just fine.
In theory I have a Johnny-HECnet bridge to psilo too, but I quit using it in favor of
the Multinet connection to MIM. I could always re-enable the bridge, providing it's
still enabled on your end, but as you say the Multinet appears to work fine.
As I remember, the "Multinet DECnet tunnel over TCP/IP" protocol is not very
complicated. Not likely that there's something wrong with it.
