Help me configure OpenSwan VPN

I need to configure OpenSwan VPN on a CentOS to connect to a Cisco ASA 5510 at a telco. I have installed the default OpenSwan on the VPS server which uses a virtual interface and TUN/TAP but have errors trying to run ipsec on the VPS server. See attached [login to view URL] and secrets files.

Also trying to run

ip tuntap add dev tun0 mode tun


/sbin/route add -net 172.28.x.x netmask [login to view URL] gw 198.x.x.x

Could anyone assist me please?
