Dropped the 2wire router and replaced with a basic Netgear one that I 
have tested with other configurations and tunnels and it has worked with 
no problems (it's a DGxxx - I forget the exact model).

What I experience now is similar to what Philippe Ritter is reporting in 
his thread "ping works but everything else doesnt".

Pings are not dropping any more in either direction. If I ssh from the 
Openswan client to the Openswan server across the Openswan tunnel, text 
streams (such as dmesg) do not hang, and I can FTP and use all remote 
apps exactly how I want. However from server-to-client (if I ssh from 
the Openswan server to the client, across the Openswan tunnel) I 
experience the hangs as Philippe Ritter describes and as I had 
originally in both directions. So it works one way but not the other.

I've just tried the iptables rules you posted yet I experience no 
difference. There's the ability to set the MTU on the DSL router itself 
- do you think that would make any difference? It's using PPPoA with a 
MTU of 1458 (which it apparently "auto detected").
