Hello Joshua and Eric,
name is David, call is CT1DRB and my qth is 15 km south of Lisbon.
I followed your instructions and my GL.INET is working more or less. In fact I have access to HAMNET, if I am connected to the router under an SSH session from computer to router. If I try to connect to HAMNET from my computer I do not get it.
Most probably I did something bad so I am here to get help from you.
Best 73 and have a nice weekend.
