I have two networks, one running beta1 and the other running t_c524. I swap them back and forth, using a Hughesnet satellite link as the ISP. With the beta network I can access the web and the status page in the satellite modem and ping the modem IP of 192.168.0.1, but with the network running the test firmware, I can ping any address on the web, and the IP of the gateway, but I cannot ping the IP of the satellite modem or access the modem status page. It looks like the IP or the associated port address of the modem is being blocked in this test version. Any recommendations? Also one other difference is that I am using a FON2200 as the gateway with the beta network, and a Meraki as the gateway with the test network. Maybe I'll try swapping the Meraki with one of the FON's.
Update: It acts the same way when I have a FON gateway. Must be something different in the test firmware..
