Hi Chris, I am able to ping and connect to my server via 44net IP address. However, I can't ping outside from the server using the tunl0 interface. I'm wondering do I need any specific configuration or add any routes if I want to connect to Internet with my 44net IP on my Debian server?

Maybe check your firewall configuration? if you want a host inside the IPIP mesh to check against you can use 44.63.7.215 73, Chris - G1FEF — ARDC Administrator Web: https://www.ardc.net On 28 Apr 2024, at 01:57, KUN LIN via 44net <44net(a)mailman.ampr.org> wrote: Hi I am wondering if the outgoing traffic can go through the IPIP tunnel gateway? After adding DNS record to my 44net ip, I can successfully ping my 44net IP. But when I try to run outbound traffic, for example ping -c 3 -I tunl0 1.1.1.1 It won't work. I am wondering how to initiate connections on the Debian 12.
