[Openswan Users] only one line of "IPsec SA established"???

[weiruyao]

IPsec SAs are unidirectional, at least two IPsec SAs are need (one for inbound traffic and the other for outbound traffic).But Why I executed "ipsec auto --status ",I only got one line of "IPsec SA established"?But the traffic is encrypted normally:I saw ESP packets going up and down happily.
