[Openswan dev] Openswan 2.4.0rc4 instability with L2TP

[Dmitriy]

I test on two kernel 2.6.12.5 versions with NAT-T openswan patch  and 
without.
results:
on NAT-T patched kernel
    openswan without nat - NOT WORK
    openswan with nat - NOT WORK
    strongswan without nat - WORK
    strongswan with nat - NOT WOK

on kernel without NAT-T patch
    openswan without nat - NOT WORK
    openswan with nat - WORK
    strongswan without nat - WORK
    strongswan with nat -     WORK

i don't understand WHY YOU PROVIDE NAT-T PATCH FOR 2.6 KERNELS?

more detail result in attachments
(i controlled nat enabling on router, and making tcpdump here - dmp files in 
attachment)
I used two ipsec.conf one with enabled nat-t, one without.
