Hello everyone, after installing cfg\_gateway.sh as in the guide [Setting up MangOH Red as Router to Cellular Gateway](https://mangoh.discourse.group/t/setting-up-mangoh-red-as-router-to-cellular-gateway/1241), I am no longer able to enter the card using the ssh root command. I tried to follow the swiflash guide but i have the following two errors : ![Error](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/3/3544693ee7d703ab2aa1218578cc60c516ce9065.png) I am using a ubuntu vm, but from windows i can see the board connected.

In cfg\_gateway.sh, you need to add "iptables -I INPUT -j ACCEPT＂ to shutdown the firewall after “iptables --flush” ```auto iptables --flush if ["$?" -ne 0]; then echo "Flush iptables failed" exit 1 fi iptables -I INPUT -j ACCEPT ``` ---

Thank you jyijyi, i will do it. My problem now is that i can’t access the board. Is it possible to reset the mangoh, or any other solution to be able to reestablish the connection through the command ssh root? Thanks in advance. ---

I can see it is working fine, I can see the modem port, NMEA port, DM port and USB ECM port. To ping the module’ ECM port, you need to go to control panel → Network and sharing Center → change adapter setting → find the “Sierra wireless LEGATO Ethlink ECM” → right click → property → click the properties of "Internet Protocol Version 4 (TCP/IPv4) → set the IP address to 192.168.2.3, subnet mask to be 255.255.255.0 ---

The problem is that you need to manually set the ip address
