We connect Windows10 PC and fx30 via Ethernet cable and want to use fx30 as a router. We were able to ping from fx30 to 8.8.8.8 referring to the ticket below. > > [”smsC hat.txt” was not created after app runProc modemDemo1 send --exe = send – 1234567“ Sim”](https://forum.legato.io/t/smsc-hat-txt-was-not-created-after-app-runproc-modemdemo1-send-exe-send-1234567-sim/5960) We connect Windows10 PC and fx30 via Ethernet cable however Windows PC does not recognize fx30 properly. Intel(R) Ethernet Connection I219-LM - IP address: 192.168.13.1 - Sub-net mask: 255.255.255.0 We collected wireshark log. [fx30\_2.pcap](https://forum.legato.io/uploads/short-url/bZemvzSbhpTlhSEpYVYEPyY2HdB.pcap) (60 KB) Do you know root cause from the log? We tried ping 192.168.13.1 -I eth0 from FX30 and ping 192.168.13.31 from Win PC. Thank you. ---

on packet 102-107, we can see the the FX30 sends out ping packet, but we don’t see any reply from Windows PC (192.168.13.1). probably this is a Windows PC problem. (e.g. firewall?) you might also try with linux PC machine and see if it can ping each other. ---

Hi @12214, Please install the WP module Windows 10 driver located on the Sierra Source. BR, Chris ---

didn’t you are trying to ping with ethernet? Is that now you switched to USB ECM interface? if so, seems to be same issue as this one: > **[Ecm disconnect in Linux](https://forum.mangoh.io/t/ecm-disconnect-in-linux/9679/3)** > > It can help me, thanks! ---

Hi cchenry, We already installed WIn 10 driver. We can confirm AT port and DM port in Device manager. And we can send AT command. Thank you ---

Hi Jyijyi, We were able to access 192.168.2.2. And we confirmed that we can ping Linux PC and FX30 or not. //Procedure// 1 ssh192.168.2.2 2 app runProc modemDemo send --exe=send – 1234567 “Online” 3 ping 8.8.8.8 from fx30 4 Connect Linux PC and Fx30 using ethernet cable. 5 ping 192.168.13.1 from fx30 (Linux PC interface eth0: 192.168.13.1) 6 ping 192.168.13.31 from Linux PC 7 Open internet browser #5 and #6 are success. please see the attached “ping.png”. ![ping](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/2X/4/441b7d9bcb2dea6d367a829279312b20577c47e0.png) In#7, we can not open internet browser. Do you have any advice?

you might have a look on this script which is working fine for mangoh red board to share radio data to ethernet client. > **[Setting up MangOH Red as Router to Cellular Gateway](https://forum.mangoh.io/t/setting-up-mangoh-red-as-router-to-cellular-gateway/1241)** > > Objective: Configure a MangOH to route cellular internet data to/from other network interfaces.

Indeed, the FX30 will not route traffic by default across interfaces. Some development is necessary to achieve this. BR, Chris ---

Hi Jyijyi, Thank you for providing the advice. Please tell us about cfg\_gateway.sh. We tried below prcedure. > > 1. Download the cfg\_gateway.sh script to the MangOH device (also found under /scripts in theMangOH GitHub) using the following: > > scp ./scripts/cfg\_gateway.sh [root@192.168.2.2](mailto:root@192.168.2.2):/tmp/. We confirm that cfg\_gateway.sh is saved to /tmp/ of FX30 after above procedure. However once power off FX30, cfg\_gateway.sh is erased from /tmp/ of FX30. Is this correct behavior? In other words, do we have to download cfg\_gateway.sh every time that we power off FX30? Thank you ---
