I'm a little confused. My ISP (AceDSL in the NYC metro area) uses, I believe, 1483, and I need no extra features to have my fbsd system talk directly to the dsl modem (Westell) over ethernet with no extra protocol layers and full 1500 mtu. I have a static IP address and a /29, and just need a default route to the ISP router's addr. The dsl modem is acting as a bridge, not a router. The routing and firewalling is done by my fbsd system. Are you talking about running the phone line directly to the fbsd box with no dsl modem? -- Barney Wolff http://www.databus.com/bwresume.pdf I'm available by contract or FT, in the NYC metro area or via the 'Net.
