TCPDUMP: 20:34:18.145815 IP (tos 0x0, ttl 3, id 32103, offset 0, flags [DF], proto UDP (17), length 158)

My setup is br-lan bridged to tap_vpn (outgoing VPN connection). Every client using TTL 4 works fine and TTL 2 is dropped in the routing chain. Any ideas what is going wrong???
Yes, it is bridged, therefore it won't be hitting iptables and there is no point in increasing TTL in a bridged network since it doesn't decrease as it doesn't hop any router.
But on my main net I have some hops so I have to increase it because of that. I like to increase hops at my client router and not central even if that would be possible too.
