Custom X750 Firmware V3.100 Custom Firewall Config

Hello,
I currently sell X750 modems running firmware 3.100. I have to manually configure each modem before giving it to a customer and it adds a lot of time. Additionally, if a customer resets the modem, I have to reconfigure it. Could someone compile a custom firmware for me?

I’m needing the following code inserted in the custom firewall: iptables -t mangle -I POSTROUTING -o wwan0 -j TTL --ttl-set 64

I would also like Remote Management to be enabled by default.

Additionally, when I set the modem up with a Verizon or AT&T SIM, sometimes the default APN is not correct. If a Verizon SIM is inserted, I would like the APN to be “VZWINTERNET”. If an AT&T SIM is inserted, I would like the APN to be “NXTGENPHONE”. (I also use T-Mobile SIMs, but the modem always connects to the correct APN: fast.t-mobile.com). Is there a way to make the modem only use these three APNs unless another is manually entered?

I would gladly pay someone to help me compile this firmware. I’ve sold over 70 X750 modems and plan on selling many more. This would help me speed up the process and sell more units.

Hi Lane,

Can you pm me your info and we could help to do something?

Hello,
Is this custom firmware option available? I am also needing the same solution.

Yes. New firmware will have ttl settings.

the current firmware version is 3.100, when can we expect the new version? really need to set up the ttl. or is there any other way to to that? BTW my device is Mudi GL-E750

If anyone is interested, I composed a version of the X750 3.104 firmware that has the TTL firewall script added, Goodcloud enabled by default, and a startup script that automatically (and correctly) assigns the VZWINTERNET, NXTGENPHONE, or FAST.T-MOBILE APN depending on which SIM is inserted. If someone wants to know how to do this, I can post a tutorial. The main issue I had was figuring out how to compile the latest firmware in the GL Imagebuilder (it would always default to an older firmware), but it’s an easy fix.

I also added more stock APN commands that are helpful in dealing with buggy connections or trying to fine tune the band/carrier aggregation settings for maximum speed.

I think I figured out my self, uninstall the luci reinstall it. than i can see the Advanced option under the more settings. log in with root and my own admin password. and than set the custom rule iptables -t mangle -I POSTROUTING -o wwan0 -j TTL --ttl-set 64
