Re: redirection trouble

[Martín]

Ok, I think I got it... but does not work. I see the traffic being 
redirected, but the conection gets lost, I got this in the snuiffer:

02:02:51.640513 192.168.2.1 > 192.168.2.5: icmp: 192.168.2.1 udp port 10000 
unrachable [tos 0x40]

Any Idea?

	Ummm what exists between the linux NAT box and the internet itself?

	Do you have another router in there? 
	what is meant by: ( eth0 192.168.1.10 > adsl ppp0 IP dinamic)
	Typically adsl direct connected routers to ppp daemons should 
	NOT have an ip on the ethernet interface unless you need to manage
	the router.  However I digress.
	
	Can you see the packet (after DNATting) on the way out ppp0?
	
	What if any other rules have you in the FORWARD chain.
	
	*thunks head on table* You will need to FORWARD the packets through the 
	box as well as DNATting the packets.
	
	iptables -I FORWARD -p udp -s 192.168.2.5 -d 200.24.24.200 --dport 10000 -j 
ACCEPT
	
	And again, depeinding on the presence of ESTABLISHED RELATED rules you may 
need to return them through the FORWARD chain

	Sometimes assumption of anything will get us in trouble.

Re: redirection trouble

I have being looking the path of packets, everything seems right. BUY i 
noticed something: the icmp port unreacheable i see and thau make the 
conection lose, seems toi originate un a firt icmp packet comeing from 
192.168.2.5 that is not being redirected to outside the NAT LINUX: Can you 
tell me hoy to redirect this kind of traffic (ICMP)

redirection trouble

[Martín]

This is the situation:



           Internal LAN machine (192.168.2.5)
                          |
                          |
                          |
(eth1 192.168.2.1) NAT LINUX ( eth0 192.168.1.10 > adsl ppp0 IP dinamic)
                          |
                          |
                          |
             Server 200.45.45.200 (service at port 10000)



This is what I intend to do:
For particular reasons, I need that a soft at 192.168.2.5 comunicate with a 
server with a service at port 10000 (UDP), but this can´t be done through 
normal NAT. So i want to establish a link between both (server and 
192.168.2.5) manually useing the NAT LINUX
So, 192.168.2.5 comunicates to 192.168.2.1 port 10000, the NAT LINUX 
redirect this traffic to the server 200.45.45.200 port 10000. The server 
will respond to the NAT LINUX who will redirect this traffic to 192.168.2.5 
(port 10000 also)
I try to do all this in this way:


iptables -t nat -I PREROUTING 1 -i eth1 -d 192.168.2.1 -p udp --dport 10000 
-j DNAT --to 200.45.45.200

iptables -t nat -I POSTROUTING 1 -o eth0 -p udp --dport 10000 -j SNAT --to 
192.168.2.5


BUT THIS IS NOT WORKING. I GET A MESSAGE FROM THE SOFT AT 192.168.2.5 
TELLING "CONNECTION TIMED OUT"... USEING TCPDUMP i get this as the only 
thing comeing back...:

200.45.45.200.10000 > 168.226.174.184.10000:  udp 8 [tos 0x40]



I would apreciate any help with this trouble
Thanks

	This line is SNATing the packet on the way out eth0 to 192.168.2.5 ,,,,, 
	This NOT what you want to do ... this packet then will look like it came from 
and went to the same ip address,

	The first line takes the packet from the source pc and DNATs it out to the 
internet ip address 200.45.45.200 ... the UNDOING of this is automatic.   
However ... what you DO need to do is 

iptables -t nat -I POSTROUTING 1 -o ppp0 -p udp -dport 10000 -j SNAT --to 
(outiside ip of firewall)

  since sending the packet out the door to the internet with the source 
address of 192.168.2.5 will cause the packet to drop dead somewhere.

   Again .. .the UNDOing of this is automatic.

Actually may be you don´t understand what I want to do. I will explain me a 
little better:

iptables -t nat -I PREROUTING 1 -i eth1 -d 192.168.2.1 -p udp --dport 10000 
-j DNAT --to 200.45.45.200


WITH THIS LINE I WANT TO CATCH THE TRAFFIC COMEING FROM 192.168.2.5 
DIRECTED TO 192.168.2.1 : 10000 AND REDIRECT IT TO 200.45.45.200
THIS LINE SEEMS TO BE CORRECT AS I CAN SEE IN A SNIFFER



iptables -t nat -I POSTROUTING 1 -o eth0 -p udp --dport 10000 -j SNAT --to 
192.168.2.5

WITH THIS LINE I WANT TO CATCH THE RESPONSES FROM 200.45.45.200 (RESPONSES 
TO THE REDIRECTED TRAFFIC I SENT FROM 192.168.2.5) AND REDIRECT THIS 
INCOMEING TRAFFIC TO 192.168.2.5
THE INGOING AND OUTGOING PORT IS ALWAYS 10000
WHAT I NEED TO DO IS STABLISH A CONNECTION BETWEEN 192.168.2.5 AND A 
SERVICE RUNNING IN 200.45.45.200 : 10000, BUT 192.168.2.5 MUST THINK ALL 
THE TIME THAT THE SERVICE IS RUNNING AT 192.168.2.1 : 10000
