You should enter all of the commands at once and save it to the firewall or click on the edit button of the firewall script and then add to it and save again. If your getting the router when you type in one of the ip's that you have 1:1 nat'd then the DNAT commands were likely erased.
The ifconfig commands can go in your startup script but you'll need to run them or reboot for them to take effect. The iptables commands all need to go into the firewall script. I would suggest running it in a shell (telnet in) first and once you have it working then save the scripts in the web ui. Also see the wiki page, it mostly just repeats things but might make more sense.
I didnt try and i'll can not until next week but is it also possible for a reason that i just can't be able to reach the server in loopback from the the same network?
I'm sorry to ask so many questions. It's just so many new parameters here.
I have Asus router N-16 with dd-wrt version 18777
I am using the built-in chilli .
my problem is that after confgiuring chilli with 3G stick it didn.t redirect me o the desired page .
I searched the Wiki and in one of the subject i found that i have to insert the following command that is missing in version 17000 - 18777 which is related to NAT .
this command is : iptables -t nat -I POSTROUTING -o `get_wanface` -j SNAT --to `nvram get wan_ipaddr`
i configured it in dd-wrt command interface and saved it in firewall .
now it redirected me to the desired page but id i press go it did nothing , giving me the error code 605 failed to connect , please try again .
