Hi all!

I try to create rule by iptables. Command successfully run, but that rule not show in list.

# iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j MASQUERADE

when i check iptables list by iptables -L command. doen't have any entry. Anybody know how to solve this problem.

Thanks
Majid

read the documentation for iptables carefully. you need to do "iptables -t nat -L" to see the rules in the nat table.

to check the command you've applied in iptables you'll apply this command

Code: Select all

# iptables -t nat -L OR iptables -t nat -nvL

Dear majidnazeer,
Salam,

When you are tying to see tables rules. You need to specify it by using -t tables-name. However by default iptables do have only three tables.

Code: Select all

1. nat
2. mangle
3. filter

You should always look into iptables documentation.

FYI, http://www.netfilter.org/documentation/

Best Regards.

Dear Farrukh!

EID MUBARAK

I use switch L for checking iptables rule. I use this command.

# iptables -L then enter

There don't have any rule mention, whenever i successfully run below command at prompt.

# iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j MASQUERADE

When i open firewall. iptables show rules on list. Why???????

Thanks

Dear majidnazeer,
Salam,

As i have told you in my last reply that you need to specify -t.

# iptables -t nat -L -n --line

Best Regards.
