Problem using ibVPN

I try to summarize:
In version 1 it works having the line “hostname_enable_nslookup = true” in the config file
In version 2 it does not work having the line “hostname_enable_nslookup = true” in the config file
In version 2 it does not work having the line “hostname_enable_nslookup = false” in the config file
By not work I mean I can not connect to the internet in Firewall mode “Ask To Connect” using ibVPN.
Is it blocked by the Firewall or is it DNS probem …? ibVPN connection is established using “Click to block” but not “Ask To Connect”.

About handling the config file I have no problem.
