Lately, I am unable to connect to my BBS via Telnet from my home computer. I
can,
however, connect to it if I log onto one of my servers and telnet or http from
that remote
computer.

I checked my log files and the home computer's IP address is not blocked. This
is a
recent occurrence although sometime in the past I could connect until I just
lost the
connection somehow.

Is anyone else having a problem with telnet or http connections? Again, I can
reach it
from other computers, just not from my own. Maybe I can whitelist the IP
address?

I'm running version A47 I believe.

I have that issue too, at times. If I am trying to go to an address inside my
own lan I will offten use 192.168.0.10 or whatever the address is. It won't
work from the outside, but works from the inside.

You have to be able to reach the destination before a whitelist will do
anything for you.

I don't know what provider you have, but if you have Comcast, their cable
modems have software which detect "threats" and will drop connections to any
system considered a "threat."

I triggered this by portscanning one of my own Digital Ocean droplets to make
sure the Firewall was behaving properly. Then I lost connection with the
droplet, although I could get it via tor, or in the method you describe.

Note that, I was scanning the remote server *from* home -- the packets bouncing
back to the port scanner were what tripped this "feature."

I had to actually write to Comcast and tell them to knock it off. This is part
of some new home security threat detection thing. I was able to reconnect in a
few days. Comcast never wrote back; I don't know if the block expired naturally
or they did something on their side.

I mention it only because it was quite recently I found myself wrestling with
this. It was irksome; I get why they think it's a good idea but probably like
most here I don't want or need their help in this regard.

If you're not using Comcast, well, forget everything I just said :)

In all these cases, are the computers all within your home network?

Can you detail the topology a bit more?

Make sure your gateway/router supports hairpinning

If it doesn't, then you'll need to use your BBS's *private* IP address when
inside your private network.

Mike, not sure if youre using Mystic BBS or not but,
Have you tried (in a shell) Mystic -l to log-in locally?

Yes, v47 It's working now after I put my IP address in the whitelist. The
system runs on a remote server, so I can't log in locally. But, if I RDP into
the server, local login works as well.
