Thanks for pointer! I will check this with DSL router I have.
There, however, might be another problem - my DSL router could be also NAT'ed 
(and most likely it is), so it draws us the following picture:

(LAN) <-NAT-> (FreeBSD) <-NAT-> DSL Router <- ??? -> ISP/Internet

Basically I'm unsure whether "???" is a normal, direct connection to internet 
via ISP, or it is also NAT'ed.
I'm most sure that it is NAT, because I've been getting one IP (e.g. my public 
IP on the net as I appear) for ~1 month (e.g. it never changed, although 
there is DHCP of course).

Well, hell knows how many further NATs I have there - at least I know about 
two already.

I guess time to visit ISP..
