when doing somehitng like ip rule add fwmark 3 nat 200.42.75.183 table ppp0 prio 1 (the idea is that packets that match the fwmark 3 change their source address to 200.42.75.183)..it first apply the nat and then routes to table ppp0 right? in such case the, nat, why may be nat not being applyed? cause it doesnt work at all..it goes to that interface but does not nat the src address of the package.

Hi, Rowland, and thanks for the reply. The PDC OS is Slackware 13. The BDC OS is Slackware 14. The choice to use Samba 4.0 was merely due to its inclusion on the Slackware 14 distro. I'll worry about upgrading that once I have the migration complete. I will post the two machine's respective smb.conf's later today. -- View this message in context:
