[aprssig] UI-VIEW tcp/ip only question

[Tim Cunningham]

We had a local user connected to Internet only this past week trying to send 
messages and ACK's from UI-View32 to RF stations. The data would not pass 
from Internet to RF or it certainly would not ACK any RF station sending a 
message to it. When they changed the TCPIP entry in their path to APRS, it 
allowed their messages to be sent as well as acknowledge those sent to it 
from the Internet to RF. It seems something blocked the TCPIP path but 
passed the APRS path. They did not try a blank entry in this case as the 
APRS TOCALL in the path worked the first time when changed from the TCPIP 
entry.

Messages sent from this user from Internet to Internet stations worked fine 
with the TCPIP entry in the path, but it would not make the journey when 
they sent messages to an RF station until TCPIP was changed to APRS.

IGate designs are supposed to block RF sending stations that have TCPIP, 
TCPXX, NOGATE, or RFONLY in the header (last 2 are optional). On the other 
hand, it is my understanding that IGates are suppose to block stations from 
Internet to RF if they contain TCPXX, NOGATE, or RFONLY in the header. I am 
referencing Pete, AE5PL's, APRS IGate Details on Gating Criteria and Paths.

The local user and the local IGate are both UI-View32 in this case. It seems 
that UI-View should have passed the TCPIP path entry from the end user. The 
data did not pass to RF until the user changed the path entry to APRS.
