TTL hop count change in firewall policy

Hello,

I am currently encountering an issue with an application, which I suspect is caused by the hop count being set too low in the TTL header. There is a FortiGate firewall in the routing path, so I am wondering whether it is possible to modify the hop count field in packets as they pass through the firewall. I noticed there is an option to change the TTL of the session in seconds; however, I have not found any articles on how to change the IP TTL header.

Does anyone know if this is possible?

Thanks.

Hello,

I am not aware that it is feasible to modify TTL hop count. Moreover, TTL hop count modification can potentially cause infinite loop in certain situations.

Oh my! I have intermittent issue but only on CentOS clients. I was looking for solution for some time now. And I had my assumptions that it must be something with the network. Now I have new clip in my gun and definitely will look into the TTL issue https://mobdro.bio/ .

Yes, I recently discovered that some applications, for reasons of their own, are designed to set specific TTL values autonomously - maybe it's your case too.
