Is the router dialling out when you try to ping an outside address?
Go to the prompt and turn on debugging for negotiation and authentication
debug ppp negotiation
debug ppp authentication
ping X.X.X.X ( ip address of internet server e.g. 159.134.237.6)
Post the output of this debug - it will help isolate where the problem is occurring.

How I will see if the router is dialing ?
ASKER
Well these are the latest...
The router can connect to the net when I send from command line a ping to an external IP.
From this moment every external IP I check responses.
Here is what the console shows when making ping to 194.219.227.2
NETLINKR#ping 194.219.227.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 194.219.227.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 36/37/40 ms
The problem is that the IE cannot open pages and also the email and other programs as DC++ from example cannot find Internet.
Should I remove the access-list? Is it a possible problem?
How can I remove it?

Don't take this the wrong way but I don't know your skillset so a couple of basics.
Is your default gateway on your pc set to 192.168.0.111?
Can you ping this address from the pc?
If you ping 194.219.227.2 from the PC, what happens?
What is listed in LAN setting in the internet options of Internet Explorer for your connection?
If you can ping the gateway, ping 194.219.227.2 but cannot browse websites then you have a DNS problem - what are your DNS server addresses? Are you being assigned them?
If you are happy that all of the above is ok, try removing the line
ip nat inside source list 18 interface Dialer1 overload
You can also confirm your connection to the internet is up by using the command
show isdn status
This will tell you if you have established a link at layer 2 and if your call is active.
