Hi
I was using UART mode PPP from the MiniMig and ao486 cores and it was working fine. I don't think I've changed anything, but they are no longer working from either.
I can connect to PPP OK, and on both cores I can ping the MiSTer's IP. I can't ping anything beyond the (router, anything else on my network, etc.).
It looks like something has gone wrong with the routing on the MiSTer side. Is there any way of checking?
An old thread suggested to add this to iptables.up.rules
Code: Select all
-A FORWARD -i ppp+ -o eth0 -j ACCEPT
I did try that and it didn't make any difference.
The only thing I can think of that I've knowingly done is added some lines to /sbin/uartmode to get faster Internet from MiniMig. I'm pretty sure that worked though as I tested it. My uartmode currently looks like this:
Code: Select all
