Thanks for that.
I don't know if this was a sheer fluke,
but when I added that from my laptop the connection to my server
was immediately broken, and after some study I found why:
IPforwarding was turned off on my server,
[root at alfred ~]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 0
I had to run
[root at alfred ~]# sysctl -w net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1
Who changes this setting, and why??
I sometimes feel there are little men inside my server
either with evil minds or else very pedantic intentions.
