Subject: 2.6.34 -> 3.0.23 regression?
Date: Tue, 06 Mar 2012 22:16:19 +0100 [thread overview]
Message-ID: <4F567EA3.5000102@arndnet.de> (raw)
Hi,
I upgraded a router box from kernel 2.6.34 to 3.0.23.
After the upgrade my proxy redirect was not working anymore
until I manually put the LAN interface (br0) in promisc mode.
Is it expected behavior that I need to set the interface into PROMISC
mode in order to get DNAT in PREROUTING to work?
With kernel 2.6.34 this was not needed...
Details:
192.168.1.1 is a router box and default gateway for clients
connected to 192.168.1.0/24 via br0,
connected to internet via wlan0,
192.168.1.2 is a proxy server running squid on port 3128
Iptables rules -t nat (simplified)
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
DNAT tcp -- !192.168.1.2 0.0.0.0/0 tcp dpt:80 to:192.168.1.2:3128
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
SNAT tcp -- 192.168.1.0/24 0.0.0.0/0 tcp dpt:3128 to:192.168.1.1
Best regards
Arnd
