Thanks @hansome at glinet , I found a way to change TTL to 65 on the repeater interface and that seem to fix the problem.
For anyone looking for the answer, here is what I have done on OpenWRT 22.03
I created a file /etc/nftables.d/12-mangle-ttl-65.nft and added the following into it. (change “eth2” for your actual tehtering interface)
chain mangle_postrouting_ttl65 {
- type filter hook postrouting priority 300; policy accept;*
- oifname “eth2” counter ip ttl set 65*
}
chain mangle_prerouting_ttl65 {
- type filter hook prerouting priority 300; policy accept;*
- iifname “eth2” counter ip ttl set 65*
}
found this info Working Nftables Rule for TTL in 22.03 - #17 by richardhd - Network and Wireless Configuration - OpenWrt Forum?
