I tried setting up a different machine here on M.I. to connect,
changed the remote IP on the Kansas City machine, and am able to
create a tunnel, ping, and ssh from M.I. to K.C., but cannot do
any of these from K.C. to M.I.
There are *NO* iptables rules on either machine at present. To
the best of my knowledge there are no IP filters between the
Internet and these machines. The one in K.C. is a DSL modem on a
/29 net block while the connection here is via an Integra/Eschelon
Adtran channel bank to a T1 to our 126.96.36.199/24 block.
I cannot understand how a connection works one way, but not the
other on what is supposed to be symmetric.
