Hi Paul,
To be honest, I did not use before openl2tp. I was reading yesterday 
about it regarding the multiple L2TP/IPsec clients behind NAT situation. 
But looks like Vyatta opted for xl2tpd.
I was testing further today the Glendale Remote Access with L2TP and 
certs scenario.
This time I've build an OpenSSL CA and issue certificates with public 
keys of 2048 bits and sha-1 as the hash function.
Things appear to be fine. IKE fragmentation occurs, but it does not 
break the connection, either behind a NAT device or directly connected.
Windows has IKE fragmentation avoidance capabilities(it announce that 
through the VID which contains the an md5 hashed value computed from 
"FRAGMENTATION", the client will switch to a “Next Payload” type 
“Private use” with a corresponding value of 132 when IP fragments are 
blocked), but it seems that Openswan does not have such capabilities.
Thanks,
Adrian
