I should have said that I am using shorewall,
which seems to work perfectly for my purposes.

I'm not really clear if there is any difference between vlan and vpn.
In any case I am running OpenVPN on the server
linking computers in 2 countries,
and this seems to work perfectly.


One obvious possibility is that the IBM Lotus "sametime" program
that is not working properly requires some port to be open;
but I haven't been able to work out which port,
if that is indeed the cause of the problem.
