I tried re running sudo ifconfig commands you mentioned before and got it to ssh into mangoh red ![Screenshot from 2020-08-18 13-45-25](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/f/fc24a15c946bf17e362c5cfea1398ed50954d8c0.png) but why is this necessary, is there anyway I can fix the naming or reassign it its default IP address, so that I do not have to take extra steps to talk to it? ---

I think if I modify the LAN configuration per the steps above when running cfg\_gateway.sh I may be able to fix the ssh issue (not sure just speculation). So I started to run it as normal and ran into this issue where it tries to bring up LAN eth0 and fails ![Screenshot from 2020-08-18 16-19-49](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/d/da8768f083448843936faea4642bc29b922a60ad.png) Why could this be? ---

seems you solved the eth0 problem. I have no idea about your “No chain/target/match by that name”. Here is my script, you can give a try.[cfg\_gateway.sh](https://mangoh.discourse.group/uploads/short-url/7LqB93zZRWDNvUXnJhZkLKpIxah.sh) (8.2 KB) ---

@jyijyi I tried using the cfg\_gateway.sh file but the APN is not compatible with my network service provider. I did not get a Flush iptables failed error this time however I am getting a new error ![Screenshot from 2020-08-20 14-44-00](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/8/80f7804aae6839986e5a3a9dc56388dab77d3d4f.png) I checked and this file is actually in the /usr/Sbin/ folder ![Screenshot from 2020-08-20 14-48-43](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/8/8f0c0729554c53c1cb446a017e4df8a76ad38c9e.png) I tried moving it to the /usr/bin folder however it says its a read-only file system ![Screenshot from 2020-08-20 14-50-02](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/5/51b3509d8ef6d946dbe3dc62e47d6e173e892733.png) I then tried to change the directory in the cfg\_gateway.sh file as such ![Screenshot from 2020-08-20 14-58-29](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/f/fa61f514c12e4e7b6cafb002096a084e2b75af44.png) and re-ran ./cfg\_gateway.sh and now it is unable to find the LAN IP Address ![Screenshot from 2020-08-20 14-59-24](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/7/75a0aa11eb00525e11baa85f9e1ab4ce9e9c28d1.png) ---
