iptable NAT/PAT inbound port forwarding without changing source address

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,


I have a problem on a NSLU2 running openwrt to do inboud portforwarding
to my internal webserver:

iptables -A PREROUTING -t nat -i ppp0 -p tcp --dport 80 -j DNAT --to
192.168.1.10

iptables -I FORWARD -d 192.168.1.0/24  -j ACCEPT



This works, however, when I look at the webserver, the traffic seams to
come from my router (192.168.1.1) and not from the IPaddress on the
internet.
I don't know why he does this as I only configured a DNAT, no SNAT.


- Is this normal? Or is this is a bug in openwrt?

- Is there a way around this?


The problem is that if all traffic comes from the router, this makes
analysis of the log-files on the webserver pretty useless.


Cheerio! Kr. Bonne.
