trying to use auth iponly

[dobcc]

i've been using strong for a bit but now I would like to switch to iponly so it's way more simple. I've been using a config and tryied many times to switch it up so it works with ip but no chances ;(.
here is the code : `
##Main##

#Starting 3proxy as a service/daemon
daemon

#DNS Servers to resolve domains and for the local DNS cache
#that providers faster resolution for cached entries
nserver 91.239.100.100
nserver 89.233.43.71
nscache 65536

nserver 91.239.100.100
nserver 89.233.43.71
nscache 65536

#Authentication
#CL = Clear Text, CR = Encrypted Passswords (MD5)
#Add MD5 users with MD5 passwords with "" (see below)
#users "user:CR:$1$lFDGlder$pLRb4cU2D7GAT58YQvY49."
ip 167.114.78.102

#Logging
log /var/log/3proxy/3proxy.log D
logformat "- +_L%t.%. %N.%p %E %U %C:%c %R:%r %O %I %h %T"
rotate 30

#Auth type
#auth strong = username & password
auth iponly

#Binding address
external 0.0.0.0
internal 0.0.0.0

#SOCKS5
auth iponly
flush
allow 167.114.78.102
maxconn 20
socks -p0001`

It works completely fine with auth strong.

If someone could help me, it would be appreciated
