Creating an IPSEC VPN between your iPhone and an AVM Fritz!Box
To create a working IPSEC VPN you need the following config file:
vpncfg {
connections {
enabled = yes;
conn_type = conntype_user;
name = "[NAME OF MY VPN]";
always_renew = no;
reject_not_encrypted = no;
dont_filter_netbios = yes;
localip = 0.0.0.0;
local_virtualip = 0.0.0.0;
remoteip = 0.0.0.0;
remote_virtualip = 192.168.178.201;
remoteid {
key_id = "[MY EMAIL-ADDRESS]";
}
mode = phase1_mode_aggressive;
phase1ss = "all/all/all";
keytype = connkeytype_pre_shared;
key = "[PRE-SHARED KEY SECRET]";
cert_do_server_auth = no;
use_nat_t = yes;
use_xauth = yes;
use_cfgmode = no;
xauth {
valid = yes;
username = "[USERNAME]";
passwd = "[PASSWORD]";
}
phase2localid {
ipnet {
ipaddr = 0.0.0.0;
mask = 0.0.0.0;
}
}
phase2remoteid {
ipaddr = 192.168.178.201;
}
phase2ss = "esp-all-all/ah-none/comp-all/no-pfs";
accesslist = "permit ip 192.168.178.0 255.255.255.0 192.168.178.201 255.255.255.255";
}
ike_forward_rules = "udp 0.0.0.0:500 0.0.0.0:500",
"udp 0.0.0.0:4500 0.0.0.0:4500";
}

Please edit the following entries:
- [NAME OF MY VPN] Whatever you like
- [PRE-SHARED KEY SECRET] This should be a very secret password (20 chars or more)
- [USERNAME] Your username
- [PASSWORD] Your password
Upload this config file to your AVM Fritz!Box (VPN Settings).
On the iPhone, you'll find the VPN config under "Settings->Network->VPN". Choose "IPSec", enter your dyndns-name under "Server". "Shared Secret" is the long password [PRE-SHARED KEY SECRET]. Voilá, your done.
