TTL expired during the transition

TTL expired during the transition what mean?

Hello,

I’m not sure, but probably ttl down to 0 an packet was droped by router. Try to set higher ttl for your packets (/ip firewall mangle).

regards

Usually means you are trying to ping an address the gateway of last resort can’t find and you don’t have a static route to. In other words, if I try to ping 192.168.0.100 on my network and don’t have a route setup to it the router will try to route it out the public gateway and give me the TTL expired error.
