[arm-allstar] Hotspot Blues -- echolink, IRLP, AllStar ports needed

[David McGough]

Hi John,

I'm not 100% clear on the config that you've got. However, below is the 
basic config you need, the IP addresses may not be right. Please excuse 
the ASCII art!

Verizon adapter (IP: 192.168.1.5)
	^
	| (usb cable)
	v	
Network Router / DMZ host (WAN IP: 192.168.1.4, LAN IP: 10.159.x.1)
	^^^
        |||
        ||| (LAN side ethernet)
        ||+-------------------------------------+
        |+--------------+                       |
        v               v                       v
BBB (IP:10.159.x.100)	RasPi (IP:10.159.x.101) PC (IP:10.159.x.z)


Note that this case, the "Network Router" should be the DMZ host, so the 
Verizon adapter should show a DMZ host address of: 192.168.1.4--the WAN 
address of the router. The LAN gateway (gateway on BBB, RasPi, etc.) 
should be 10.159.x.1, the LAN address of the "Network Router".

The last step would be to config the "Network Router" to perform 
selective port forwarding to the BBB and RasPi, as mentioned in the 
earlier post.

....I hope this helps and the diagram survives the list server.
