Is this site still valid?
Specifically this? In the 'new way of things' will I still see traffic
from amprgw.ucsd.edu?
tcpdump -i enp3s0 -vvv host
amprgw.ucsd.edu or ip proto \\icmp
Because I'm not seeing anything here from amprgw. Though I'm just monkeying with
it the first time now, so could just be 'new user stupid'
ifconfig tunl0 up 44.4.28.50 netmask 255.255.255.255
ip rule add to 44.4.28.50 table main priority 44
ip rule add dev tunl0 table 44 priority 45
ip rule add dev enp3s0 table 44 priority 46
ip rule add from 44.4.28.50 table 44 priority 47
