Re: [squid-users] TPROXY Squid Error.

tcpdump shows traffic flowing both ways, which is good. We also need
to have the following settings:

# sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 0
net.ipv4.conf.all.rp_filter = 0
net.ipv4.conf.eth0.rp_filter = 0
net.ipv4.conf.eth1.rp_filter = 0

The last two lines are for my specific system where I have two NICs.
Feel free to modify on your own. After changing the file running
"sysctl -p" usually works. To check if it did, please run the
following commands:

find /proc/sys/net/ipv4/ -iname rp_filter
find /proc/sys/net/ipv4/ -iname rp_filter -exec cat {} +

The first shows all the rp_filter in your system.
The second shows if they are indeed set to 0 as needed.

Please do a pastebin for both sysctl.conf and the outputs of the find commands.

Regards
HASSAN
