Does your NAT gateway have some inbuilt SIP feature? For example - a SIP ALG on it? If
yes, try disabling it.
Also check if you have set any port forwarding rule on your NAT gateway for port 5060.

Great!!
this actually worked. I've changed the port from 5060 to 5070 and now
authorization runs fine. Could anyone give a logical explanation for this?
thanks again Mike,
Bart

One thing... some routers think that they are very smart :),
so try to change port on SER from 5060 to some other ( like:
port=5070 ) most of routers can be fooled with it.
