Bridge/Ipf Related

[CruzKennie_(_at_)_aol_(_dot_)_com]

Dear Users,

I configured a bridging firewall using OpenBSD and the old ipfilter that was 
distributed with the 2.8 version of the OS. It has around 3 to 4 months 
working for the our Department. We recently found and error with netbios, it 
is imposible to authenticate netbios systems that are not on the same subnet.

Now, I don't know if this problem is related to the ipf code or the briding 
code. I had checked my ipf rules over and over again I don't see to find 
anything usefull or hint about my problem. Any help will be appreciated.

I am desperate, cause' my supervisor want to change my perfectly working 
firewall with a netfilter/linux firewall.

Thanks in advance.
