[Openswan Users] checkpoint NG AI and Openswan 2.1.2

[Ji Hui]

Hi,

I was trying to configure site-to-site VPN with my partner who is
using Checkpoint NG AI R55.

I could establish the VPN from openswan to NG, but the other direction
is failed. And sometime, the packets were dropped by NG, complaining
no valid SA.

Any advice? 

thank you.
