Error: Rate Limiting only available with ACCEPT, DNAT[-], REDIRECT[-] and LOG
I think it would be nice to be able to rate limit an action, too..
suppose I have an action named Accept_good_source :
ACCEPT - - tcp - 1024:65535
ACCEPT - - udp - 1024:65535
and that i want to use it in an action called AllowCVS,
i can''t limit the cvs usage, but only the general use of 
Accept_good_source...
same goes for userset...
as each rule will give one iptables command,

Rate limiting
I am trying to rate limit a particular user/ip''s news traffic and have
added the line 
 
ACCEPT          loc:10.5.75.253           net     tcp     119     -
-       1/sec:2
 While this has slowed down the traffic, it has not throttled it to the
point I would like. 
Yet with a sniffer I can see around 15 packets a second going thru. My
T1 is close to saturation, and I would like to

Multiple Internet connections with Dynamic IP addresses
Cristian and Alex,
Both of you have asked about this. A routing table can only have one default
route so when the second link comes up, adding the second default route will
fail. So in general, Shorewall can only reliably detect the gateway for
P-T-P connections which is what the CVS current code does.

Reflecting internal connections to public IP back into network?
I''ve got a Shorewall firewall setup that''s similar to the standard 3
interface configuration (net,loc,dmz). Several ports are forwarded from the
internet to computers in the dmz. I''d like to have any connections to that
same public IP address from either loc or dmz to be treated exactly as if
they were coming in from the internet itself.

Question about ip_forward in clear_firewall
Firewall users,
   My apologies as I''m not on this list, so please respond directly as 
well as to the list. I did try to search the archives and didn''t find 
any hits, although the search did not like searching for terms with 
underscores in them (both clear_firewall and ip_forward).
I was trying to understand why, when running shorewall stop, even though

shorewall friendly way of limiting ssh brute force attacks?
I was wondering if anyone had implemented rules like this in shorewall:
http://blog.andrew.net.au/tech
I see tons of brute force attempts on the machines I administer, and I like
the idea of limiting them without the need for extra daemons scanning for
attacks.
Thanks,

MAC address verification limitation
hi there. There are approx. 400-500 users in our
network and we plan to insert all their MAC addresses
into maclist and bind them together with IP address.
My question is whether shorewall is able to process
that much of MAC addresses without slowing the the
network speed performance? thanks for your time.

Public IP issues
I have had Shorewall 2.0.8 up and running for a month or so. Now I need
to change some things around. Currently I am running on a private IP
scheme and Shorewall is setup based on the 3 interface guide. Now I want
to change to a public scheme on my "loc" zone. I have a /24 block of
public IP''s. I need my private scheme and public to co-exist so I
currently have is eth1 (local)

Bridge Interface without an IP Address?
We are using Shorewall 2.0.8 with SuSE 9.1 and have built a bridging 
firewall primarily to defend against syn flood and smurf DoS attacks.
We are a small ISP using Cisco routers for a total of 5-6 subnets.
Since bridges are based on use of MAC addresses, if we could use one 
bridging firewall system instead of 5-6 ... is this possible? practical?

ip rule to block ssh attack
I''ve found the below rule, is it possible to use it with shorewall?
I see how to setup the timing/rates but how to perform loggin of such action (a separate rule?).
as an additional question is i possible to dynamically add hosts to blacklist and persist this between restarts?

How do I limit download speed by ip address on the LAN?
Hello there,
 
I can modify /etc/shorewall/tcdevices to control overall IN-BANDWITH. It is quite effective. Just change 2mbit to 128kbit.
 
However, how do I limit download speed for a certain host IP on the LAN? I want to limit host 192.168.1.140 download speed to 128Kbit. Other hosts on the 192.168.1.0 LAN can still surf at 2mbit.
 
Any input welcome.
 
Kind Regards,
