(Solved) iptables Entry Not Applied 86U 384.8

[GHammer]

I am trying to get traffic from one device to be available at a second device so I can sniff for certain packets. The traffic from the first device still needs to continue, not just be forwarded to the second device.

I believe these are the iptables entries I need to do this. However, entering them directly or using a script does nothing when I list iptables.
I'm sure I have went wrong somewhere, but where?

/jffs/scripts/firewall-start
#!/bin/sh
iptables -t mangle -A PREROUTING  -s 10.10.100.121 -j ROUTE --tee --gw 10.10.100.115
iptables -t mangle -A POSTROUTING -d 10.10.100.121 -j ROUTE --tee --gw 10.10.100.115

Results after firewall restart (service restart_firewall):

Oct 27 12:17:22 custom_script: Running /jffs/scripts/firewall-start (args: eth0)

admin@RT-AC86U-6828:/tmp/home/root# iptables -L | grep 115
admin@RT-AC86U-6828:/tmp/home/root#

Try:

iptables -t mangle -L -n | grep 115

Try:

iptables -t mangle -L -n | grep 115

Thank you! Works fine.
I couldn't imagine why it wasn't listed.

without a -t argument, iptables -L will show thhe filter table, your rule was adding to mangle.
