Fix ttl on LEDE Hsairpo CP200

Plis help .. how to change ttl on openwrt LEDE in terminal??

The first fix would be upgrading to a (security-) supported version of OpenWrt (22.03.5 or newer).


What is the device that you are using? It appears it is not supported by the OpenWrt project and what you have installed is likely a highly modified version of 17.01 that is not from the LEDE/OpenWrt project.


…not just highly likely, but guaranteed.


Im use hsairpo cp200

does it matter ?

the previous replies still apply.

Must update? How to update

you can't, AFAIK the device isn't supported, here.

Ok sir thanks

I also HSAirpo CPE200 user.. waiting for good news.
I hope this can be upgraded to 22.03.5

It's simply not happening, these devices will be EOL:ed after the current release.

I just found a way,
using winscp (windows software)
and try connecting using SCP protocol dont using SFTP
login as root and password is admin
Be careful in the file manager. then go to /etc/firewall.user then open the file and edit it as in the example
enter code

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

after that go to ssh terminal and write
service firewall restart

Yes, your modem has been fixed to TLL 65
