[Openswan Users] ASA multiple subnets problem

[Hickman, Daren]

I have openswan ver 2.6.28 connecting to an Cisco ASA 5510's running version 8.4.  The openswan side has 1 subnet and the ASA side has four subnets so 4 tunnels are expected but only one tunnel comes up.  The cisco gives error processing payload; payload ID 1.  The openswan gives received and ignored informational payload No_Proposal_Chosen msgid=00000000


The openswan side of the connection is



conn CHRSUB
        authby=secret
        auto=start
        phase2=esp
        phase2alg=aes192-sha1;modp1024
        ike=aes192-sha1;modp1024
        left=166.251.X.X
        leftsubnet=172.31.6.0/24
        leftupdown="ipsec _updown --route yes"
        pfs=no
        right=216.77.X.X
        rightsubnets={10.1.0.0/16 10.20.30.0/24 10.4.1.0/24 172.22.0.0/24}
        rightupdown="ipsec _updown --route yes"
        type=tunnel
