Change outgoing TTL

AdamK · 2024-02-29T04:55:37.370Z

Yes. I tried 65, 66, 117. And now I just upgraded my Mudi to firmware 4.39 and I can’t access 192.168.8.1 anymore…

Does the LCD display that the router is booted?

AdamK · 2024-02-29T04:58:11.934Z

Yes, it’s normal. “Insert SIM Card and Reboot”. I am connected to the Mudi’s Wi-Fi and I previously had it setup in repeater mode wired connected to my Verizon Inseego M3100 modem.

I am on 4.3.9 and seems everything is fine. Do you still get valid IP 192.168.8.x from it

AdamK · 2024-02-29T05:01:24.272Z

I can’t connect to the gateway and see anything. The internet connection via the wired connection to the M3100 modem still works, but I just can’t access 192.168.8.1 anymore, nor ping it. I was previously on 3.x firmware and now I’m screwed.

Can you just rest using the reset button?

Press and hold for 10 seconds, release, and watch the screen message

AdamK · 2024-02-29T05:51:02.473Z

Thanks, that worked. Interestingly the firmware reset landed me on 4.0.0. And I can’t seem to get the modem to connect fully to the Verizon tower using my nanoSIM. Will troubleshoot more tomorrow.

EDIT: Firmware 4.0.0 does not work with my Verizon SIM. Downgrading back to 3.217 gets it connecting again. Now back to troubleshooting the throttling bypass…

I have SpitzAX where there's the option to set the TTL for the sim card under manual setup. Shouldn't I just use the default (eg 64) instead of 65, since it connects to the cell tower directly like a phone, instead of going through a mobile hotspot first?

Also when using network analyzer pro, should I use the TTL from ping (54) or traceroute (first hop, 254)? Ping seems to return the last hop from traceroute (54).

Also if my VPN is always on, can the telco see the packets from other devices connected to the router?

So this was working quite well with GL-SFT1200 and my S22u on Verizon network, but as Friday morning as I was periodically checking my account I noticed balance was suddenly be accounted to my hotspot.

I have tried this and other command lines and nothing, i can ping from my laptop and everything comes back as TTL of 65.

You can do a really easy test on Verizon to see if they think your browsing from your phone, and that's to hit fast.com, which should be capped to 5mbps and under. My phone reported 4.1mbps, my laptop connected to the router, 70-90mbps.

I changed the TTL on my laptop, and if I connect right to my phone that way, and boom 4.5mbps. So Verizon is not doing DPI.. yet, but something is suddenly off with the router and I never touched any settings.

tries on yes ft5g. ttl set to 64 either in custom firewalls or webgui, it works for windows only after set windows netsh to 65. but not works for mobile. any idea?

alzhao · 2024-09-16T04:10:12.127Z

In the latest firmware should just change via the UI. Pls confirm your firmware version.
Also check if you have ipv6 and need to set the HL.

Set to 65 on the router.

Trigon:

GL-SFT1200 and my S22u

Are you using USB tethering or repeater?

How did you set?

konvertek69 · 2024-09-18T08:00:12.378Z

It works. Thank you

Trigon · 2024-09-20T00:57:25.507Z

I have tried both Repeater/Tethering. Also still setting 65 on my laptop now, does not work any more.

crackers8199 · 2024-12-27T03:01:32.324Z

how'd you get this to work on the beryl? i've tried 64, 65, and 66 via iptables and nothing is working on tmobile via iphone tether (or repeater). everything is getting allocated to hotspot data.

crackers8199 · 2024-12-27T03:01:45.667Z

what's the trick to get the beryl ax working via iphone tether (or repeater)? seems everyone thinks TTL 64 or 65 should work, but neither one works for me.

bruce · 2024-12-27T03:26:51.209Z

If the GL GUI display the USB devices (ios) but cannot establish the connection?
If established the connection but the IP always getting?
If GL router can get an IP but actually no Internet connection, which the clients cannot access the Internet.
SSH to the router, ping the tethering gateway IP.
Confirm whether the mobile SIM package supports network sharing, can connect your phone to the PC to confirm the availability.
If the PC works but router does not work, please let me know the iPhone model, iOS versions, GL firmware version.
Please PM me the syslog.

I haven't used it in a while, but I had added these to the startup in Luci. Also think I had to disable ipv6.

iptables -t mangle -I POSTROUTING 1 -j TTL --ttl-set 65

iptables -t mangle -I POSTROUTING 1 -o eth1 -j TTL --ttl-set 65

iptables -t mangle -I POSTROUTING -o usb0 -j TTL --ttl-set 65

crackers8199 · 2024-12-29T23:28:29.340Z

i had tried some version of this, but only with the first command. are the other two necessary to make it work 100% of the time? it definitely did not hide hotspot traffic with just the first mangle rule in place.

crackers8199 · 2024-12-30T20:01:04.216Z

this definitely does not work at the moment. used these rules and then tethered my iphone via USB to the beryl and it counted everything as hotspot data.

is there a way to make this work now or is this dead?
