iptables does not list rules i have created
24,009
Solution 1
The command iptables -nvL
is displaying the contents of the filter
table. The rule you are adding is in the nat
table. Add -t nat
to look at the nat
table:
iptables -t nat -nvL
Solution 2
You can also run iptables-save
and it'll dump all the contents to the screen if you just want to look at everything. I find it easy to look at everything that way when I feel lazy.

I'm using this guide to set-up a shared internet connection between two PC's.
At step 8 it says I should run the commands:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE /etc/rc.d/iptables save /etc/rc.d/iptables start
Doing this seems to have no effect on iptable's rules, if I run
iptables -nvL
my output is:Chain INPUT (policy ACCEPT 2223 packets, 2330K bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 2272 packets, 277K bytes) pkts bytes target prot opt in out source destination
Is that correct or am I doing something wrong?

Doctor almost 4 yearsI don't get why my INPUT rule does not appear when I use
iptables -L
but does show up when usingiptables-save
. Makes no sense. -
John Mitchell almost 4 yearsiptables-save just dumps everything but iptables -L (without the -t directive) defaults to JUST showing your filter table. There are 3 other tables which CAN be listed linux.die.net/man/8/iptables
