I added the -a options to ampr.sh as you recommended. No change after restarting it.As
far as the router IP, in DMZplus mode, the AT&T router/modem actually assigns (via
DHCP) the external address to the selected device, in this case my ER-X. So the ER-Xs
DHCP- assigned address is 23.118.163.99.Sent via the Samsung Galaxy S9+, an AT&T 5G

DMZ, but usually there is a DMZ host defined in your ISPs router, which is part of your
internal network. You need to set that specific address in the ampr-ripd line in ampr.sh
as a option.>> eth0 on the ER-X is the WAN connection to the modem. eth1/3/4 go to

the gateway also publishes 44.0.0.1/8, which is interfering with the routing, acting as a
catch-all for 44net, preventing access to your local ampr LAN.>> I also installed

right???That status will show up even if you send your "presence" via regular
internet, so it can't be used as an indicator of the system working properly.>>
Here are my problem observations, however:>> - I cannot seem to access anything on
