GL.Inet TTL Change

I use a GL-X750 for internet access while I travel, and while I have an unlimited dataplan is seems some carriers in the us play funny buggers and “de priortise” data from secondary devices. I have found this work around to function for me…. we are changing the TTL of all connected devices, so its harder for the carrier to work out what device is what.

  • Step 1: Login to your device
  • Step 2: More Settings -> Advanced
  • Step 3: Login again
  • Step 4: Network -> Firewall
  • Step 5: Custom Rules -> Add entry
  • Step 6: Restart

Step 1: Login to your device

Login

Step 2: More Settings -> Advanced

Advanced Settings

Step 3: Login again

Yes – the username will be root, the password will be your admin password. Your path will be https://x.x.x.x/cgi-bin/luci

Login 2

Step 4: Network -> Firewall

Firewall

Step 5: Custom Rules -> Add entry

You want to click on custom rules, then go right to the bottom. Here add this line:

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

Step 6: Restart

Once done, click on the restart firewall, and you should be set after a reboot. This worked for me, your milage may vary.
