NAT IPFilter

Hi everybody,
I'm running on Solaris 10 X86 (update 1009).
I would like to make NAT's rule. I explain you.
On Solaris, I configure the principal interface e1000g0 with IP : 192.168.0.33

I created the first logical interface like that :

Code:
ifconfig e1000g0 addif 192.168.0.40 netmask 255.255.255.0 up 



and the second like that :

Code:
ifconfig e1000g0 addif 192.168.0.41 netmask 255.255.255.0 up 



I have on a Linux Redhat 5.4 a FTP server and a WEB server with IP 192.168.0.1

What I wanted to do, is to map the address 192.168.0.33 to the logical 192.168.0.40 when I connect to the FTP on 192.168.0.1 and to map the address 192.168.0.33 to the logical 192.168.0.41 when I connect to the Web server on 192.168.0.1

I know how to map :

map e1000go 192.168.0.33 -> 192.168.0.40

But I don't know how to map to the logical IP address according to the port 21 ou 80

I look to the man page of ipnat but I don't know if it's possible

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)

ipfilter blocking ip fragments

For some reason ipfilter is blocking inbound fragmented ip packets (the packets are larger than the interface's MTU) that are encapsulating UDP segments. The connection works, so I know ipfilter is letting some traffic through, it is just a lot slower than it should be. Rules that allow the... (3 Replies)

NAME
ipnat - user interface to the NAT subsystem SYNOPSIS
ipnat [-dlhnrsvCF] -f filename The ipnat utility opens a specified file (treating - as stdin) and parses it for a set of rules that are to be added or removed from the IP NAT. If there are no parsing problems, each rule processed by ipnat is added to the kernel's internal lists. Rules are appended to the internal lists, matching the order in which they appear when given to ipnat. ipnat's use is restricted through access to /dev/ipauth, /dev/ipl, and /dev/ipstate. The default permissions of these files require ipnat to be run as root for all operations. ipnat's use is restricted through access to /dev/ipnat. The default permissions of /dev/ipnat require ipnat to be run as root for all oper- ations. The following options are supported: -C Delete all entries in the current NAT rule listing (NAT rules). -F Delete all active entries in the current NAT translation table (currently active NAT mappings). -d Turn debug mode on. Causes a hex dump of filter rules to be generated as it processes each one. -f filename Parse specified file for rules to be added or removed from the IP NAT. filename can be stdin. -h Print number of hits for each MAP/Redirect filter. -l Show the list of current NAT table entry mappings. -n Prevents ipf from doing anything, such as making ioctl calls, which might alter the currently running kernel. -s Retrieve and display NAT statistics. -r Remove matching NAT rules rather than add them to the internal lists. -v Turn verbose mode on. Displays information relating to rule processing and active rules/table entries. /dev/ipnat Link to IP Filter pseudo device. /dev/kmem Special file that provides access to virtual address space. /etc/ipf/ipnat.conf Location of ipnat startup configuration file. /usr/share/ipfilter/examples/ Contains numerous IP Filter examples. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWipfu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ ipf(1M), ipfstat(1M), ipnat(4), attributes(5) To view license terms, attribution, and copyright for IP Filter, the default path is /usr/lib/ipf/IPFILTER.LICENCE. If the Solaris operat- ing environment has been installed anywhere other than the default, modify the given path to access the file at the installed location. 25 Jul 2005 ipnat(1M)
