      Hi.

      We tried to establish a VPN Connection for "Road Warriors" just like the Tutorial will be called. We had serveral problems receiving an answer from the VPN-Server.

      I tried some Clients (ios, win, linux, mac) … nothing worked and everywhere is the same problem.

      I use the same settings as in the tutorial

      here is my ipsec config:

      
config setup
	uniqueids = yes

conn bypasslan
	leftsubnet = 192.168.1.0/24
	rightsubnet = 192.168.1.0/24
	authby = never
	type = passthrough
	auto = route

conn con1
	fragmentation = yes
	keyexchange = ike
	reauth = yes
	forceencaps = yes
	mobike = no
	rekey = yes
	installpolicy = yes
	type = tunnel
	dpdaction = clear
	dpddelay = 10s
	dpdtimeout = 60s
	auto = add
	left = 80.150.xx.xx
	right = %any
	leftid = 80.150.xx.xx
	ikelifetime = 86400s
	lifetime = 28800s
	rightsourceip = 192.168.123.0/24
	ike = aes128-sha1-modp1024!
	esp = aes128-sha1!
	leftauth = psk
	rightauth = psk
	rightauth2 = xauth-generic
	leftsubnet = 0.0.0.0/0

      and the error log:
