Subject: Explicit source port mapping
Date: Wed, 1 Nov 2006 16:24:21 +0100 [thread overview]
Message-ID: <200611011624.21822.andreas.micklei@ivistar.de> (raw)
Greetings,
I have an unusual (maybe?) request. I have several private IPs (192.168.x.x)
behind a Linux gateway. All are NATed to the Internet. Now I want to
explicitely map each private IP to a fixed source port range on the WAN
interface of the gateway.
Example:
Connections from 192.168.42.1 are mapped to source ports 1024 - 1279
Connections from 192.168.42.2 are mapped to source ports 1280 - 1343
Connections from 192.168.42.3 are mapped to source ports 1344 - 1408
...
Quetions 1: Can netfilter do this for me?
Question 2: If not, would it be easy to implement, and can someone give a
suggestion where I should start? - Or even better: Has someone already
implemented this?
Sorry if my question sounds stupid. In the HOWTOs I could only find implicit
source port mapping. Also I did not find a search interface for the
mailinglist. So if this question is already answered, pointers are
appreciated.
regards,
Andreas Micklei
