[Openswan Users] packet format with klips 2.3.1 and klips 2.4.2dr1

[Marco Berizzi]

Hello everybody.
I have a problem with klips 2.4.2dr1 with linux 2.4.31
The problem isn't related to userland tools version,
only KLIPS version.
Our ISP router is configured with some kind of QoS to
give priority to VoIP traffic. This QoS is implemented
on source IP packet. I have no control over this router.
Briefly: KLIPS 2.3.1 is working ok. KLIPS 2.4.2dr1:
connections are frozen in Phase 1.

Is there any packet format/flow change between KLIPS
2.3.1 and KLIPS 2.4.2dr1?

Running KLIPS 2.3.1 + userland 2.4.2dr1 are fine.
