After excessive reading various linux networking manuals and asking a lot of friends I found the solution to my problem which may seem tiny and unimportant to most users on this board: I had to add a route, via:
Code:
route add default gw 192.168.2.1
Using this additional setting seems to work for me - not knowing though if this is opening a big hole in my network security (especially my ASUS router). I hope not. If there is another newbie like me with the same problem, I hope I could help him or her.
Thanks for reading.
