I do exactly that with a Zyxel 660 - One of it's NAT configurations lets = you set multiple external addresses as one to one or many to one NATable setu= ps. So I map my external servers one to one and all the rest goes through a sing= le many to one. Works a treat. I used to have the real world IPs go straight= through, I have 8, but I had more machines than addresses so there was a = NATted network via a Sparc box - but it actually meant that although all boxes c= ould get out to the 'net they could not all talk to each other. This snazzy mu= lti NAT setup solves everything as the LAN side is just one 192.168.0 net. -- Regards Dave Saville =3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D= -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D This message is sent to you because you are subscribed to the mailing list .
