We've added a couple of new boxes to the internal network (192.168.1.100, .101) and want to be able to get to port... (1 Reply)

Hi All,
Is there any possibility to change the IP address of a package according to its MAC address. It would be a sort of L2 NAT. (i.e. If the MAC address is 00:1A:A0:1E:XX:XX so the dir IP will be 192.168.X.X)
Thanks!. (4 Replies)

Hi All!
I have a Pentium 100 (32 MBRAM) with FreeBSD 4.4 installed on it and I am using it as a gateway. When I am downloading (or uploading) stuff simultaneously I see that natd is using up to 100% of the cpu capacity, hence the internet connection becomes blocked.
My guess is I will have... (1 Reply)

IPNAT(8) System Manager's Manual IPNAT(8)
NAME
ipnat - user interface to the NAT subsystem
SYNOPSIS
ipnat [ -dhlnrsvCF ] [ -M core ] [ -N system ] -f <filename>
DESCRIPTION
ipnat opens the filename given (treating "-" as stdin) and parses the file for a set of rules which are to be added or removed from the IP
NAT.
Each rule processed by ipnat is added to the kernels internal lists if there are no parsing problems. Rules are added to the end of the
internal lists, matching the order in which they appear when given to ipnat.
Note that if ipf(8) is not enabled when NAT is configured, it will be enabled automatically, as the same kernel facilities are used for NAT
functionality. In addition, packet forwarding must be enabled.
OPTIONS
-C delete all entries in the current NAT rule listing (NAT rules)
-d Enable printing of some extra debugging information.
-F delete all active entries in the current NAT translation table (currently active NAT mappings)
-h Print number of hits for each MAP/Redirect filter.
-l Show the list of current NAT table entry mappings.
-n This flag (no-change) prevents ipf from actually making any ioctl calls or doing anything which would alter the currently running
kernel.
-p This flag is used with the -r flag to cause any active NAT sessions that were created by the rules being removed and that are cur-
rently active to also be removed.
-r Remove matching NAT rules rather than add them to the internal lists.
-s Retrieve and display NAT statistics.
-v Turn verbose mode on. Displays information relating to rule processing and active rules/table entries.
FILES
/dev/ipnat
/usr/share/examples/ipfilter Directory with examples.
