Many thanks for this and all other replies. The problem was indeed down to MTU issues: exactly what the fix was in the end I'm not sure. I'll ask Nick tomorrow when he's not being a vet then let you know.

The problem was adding a Linksys RT31P2 router using NAT as supplied by vonage into a system where large file transmits were being done using openvpn.
It seems that forcing fragmentation of full openvpn packets (mtu 1500) by degrading the mtu in the router (mtu 149x) solved the "waiting for ever" problem. I suspect that the waiting-for-ever was due to udp packet loss that went unrecognised by openvpn for some reason.
There is no satisfactory full "deep" explanation as yet.
