I have not got my copy of "Internetworking with TCP/IP Vol. x" with me = (someone borrowed it indefinatly) so forgive this rather basic question. I have a rule, very early in my ruleset that says: deny log ip from any to 10.0.0.0/8 via xl0 but my gateway (and default route) is 10.0.0.100 Now, it's working the way I want it to... In that it sends outside = stuff to 10.0.0.100 and I can't telnet directly to the gateway. But I = am curious why this rule does not get inforced. What does a TCP packet look like when it's being sent *to* a remote = destination, but via a gateway. Does the ip stack translate 10.0.0.100 = to an ethernet address and pass it on that way? -D -----------------------------------------------------------------=0A= ATTENTION:=0A= The information in this electronic mail message is private and=0A= confidential, and only intended for the addressee.
