I might be wrong, but I don't think we ever supported rdr without net.inet.ip.forwarding enabled. Maybe to a different local address, but even then you'd need net.inet.ip.check_interface=0. Looking at the code, I don't see where IPFW forwarding fails (as it has its own ip_forward() call), though. -- /"\ Best regards, | [EMAIL PROTECTED] \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | [EMAIL PROTECTED] / \ ASCII Ribbon Campaign | Against HTML Mail and News _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
