Linux-BSD Ipsec VPN

I need to establish from a Linux firewall to a FreeBSD server.  I have successfully installed FreeS/Wan, but am quite confused as to what IP address I put where.  If someone is kind enough to provide a working ipsec.conf file for this connection, I'll give bonus points.  I have this tidbit of info from the side that I'm trying to connect to.  It was originally designed for a racoon BSD client:

spdadd 172.27.224.0/24 10.11.58.0/24 any -P out ipsec
        esp/tunnel/207.109.153.102-208.61.77.133/require;
spdadd 10.11.58.0/24 172.27.224.0/24 any -P in ipsec
        esp/tunnel/208.61.77.133-207.109.153.102/require;
 
#spdadd 207.109.153.105 10.11.58.1 any -P out ipsec
#        esp/tunnel/207.109.153.102-208.61.77.133/require;
#spdadd 10.11.58.1 207.109.153.105 any -P in ipsec
#        esp/tunnel/208.61.77.133-207.109.153.102/require;
 
spdadd 207.109.153.103 10.11.58.1 any -P out ipsec
        esp/tunnel/207.109.153.102-208.61.77.133/require;
spdadd 10.11.58.1 207.109.153.103 any -P in ipsec
        esp/tunnel/208.61.77.133-207.109.153.102/require;
 
spdadd 207.109.153.98 10.11.58.1 any -P out ipsec
        esp/tunnel/207.109.153.102-208.61.77.133/require;
spdadd 10.11.58.1 207.109.153.98 any -P in ipsec
        esp/tunnel/208.61.77.133-207.109.153.102/require;
 
Here is our config setup:
 
remote anonymous
{
        exchange_mode aggressive,main;
        doi ipsec_doi;
        situation identity_only;
 
        nonce_size 16;
        lifetime time 1 hour;
        initial_contact on;
        support_mip6 on;
        proposal_check obey;    # obey, strict or claim
 
        proposal {
                encryption_algorithm 3des;
                hash_algorithm sha1;
                authentication_method pre_shared_key ;
                dh_group 2 ;
        }
}
 
sainfo anonymous
{
        pfs_group 1;
        lifetime time 1 hour;
        encryption_algorithm des, 3des;
        authentication_algorithm hmac_md5, hmac_sha1;
        compression_algorithm deflate ;
}

Cheers,
