[44net] UCSD tunnel persistence across reboots?

Hello! I've been working on getting my IPIP mesh gateway set up on Debian & feel like I'm almost there. One thing I’ve noticed is every time I reboot the router, it takes around 45-60 minutes before I can start passing traffic to the public internet again via the ucsd gateway. For example, after rebooting the router, once rip44d has retrieved the routes I can: (a) Ping and curl across tunl0 to n2nov.ampr.org (b) Use yo2tm’s nettools to successfully ping my ampr ip and see that traffic locally via tcpdump But cannot: (c) Ping 8.8.8.8 across tunl0 (via 169.228.34.84) or (d) Curl to ifconfig.me across tunl0 (via 169.228.34.84) However, if I just leave everything running and come back 45-60 minutes later, (c) and (d) work fine with no additional configuration changes and (d) returns the assigned 44net ip address. Just curious if the above is an expected behavior or a sign that I’ve got something misconfigured. -Steve kc8qba
