I have ADSL line with subnet mask (giving me 4 IPs, but only
2 usable really)

I seems not to be able to figure out how I could use BM connected to ADSL
line with Netgear router (all firewall functions turned off)
Router has an PUBLIC-real IP on its public site as well as on its private &
BM is to have also PUBLIC-real IP on its public interface.
That makes already 3 real IP addresses, right?

I have the exact same setup on my other ADSL line with BM & it works
