Hi, this is my first message to the mailing-list. I hope that I have
included
enough information about the problem.
The problem is that my FreeBSD 6.0 (release) won't use the default route
(gateway). So I can't access anything on the internet.

I may have snipped some clue to what's actually wrong, but don't let
that discourage you from trying to file complete problem reports.
I'm a snipper. What I found to be most relevant follows.
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 192.168.0.199 UGS 0 52 bge0
[snip]
This shows generally that the router IP is being properly used by
FreeBSD as a gateway (Use = 52). Suggests that your assumption that
FreeBSD isn't using the gateway properly is not correct.
alcoy# traceroute ping.sunet.se
traceroute to ping.sunet.se (130.242.80.31), 64 hops max, 40 byte packets
1 sentinel (192.168.0.199) 0.524 ms 0.518 ms 0.515 ms
[snip]
This shows the gateway IP is being properly used by FreeBSD as the
appropriate route to ping.sunet.se. Indicates that the problem
really is not FreeBSD's default route configuration or
functionality. The route is clearly being used.
alcoy# ping sentinel
PING router.aqualize.tk (192.168.0.199): 56 data bytes
64 bytes from 192.168.0.199: icmp_seq=0 ttl=250 time=0.669 ms

This shows you communicating with the gateway directly (confirms the
assertion that local LAN operations are doing just fine).
Since your packets are being routed and NATed by the gateway
correctly when the box is in Windows mode, packets should be getting
routed and NATed correctly for FreeBSD as well. That is, if the box
in Windows mode is using the same IP number and mask as the FreeBSD
settings (you should double check that it is).
If the gateway is running fine (seems to be) and FreeBSD is properly
using the gateway (seems to be), then the most likely suspect seems
to be firewall configuration -- after your connection is properly
routed, reply packets from the Internet could be getting dropped on
the floor by your gateway or by FreeBSD.
Have you configured any kind of packet filter (ipf, ipfw, other) for
FreeBSD? Try disabling that and see if your results change. If so,
tune your filtering rules accordingly.
Use of tcpdump -i bge0 may also be informative (see man tcpdump).
