I am trying to downgrade an SD card to R7. I took a new card, reformatted it, recreated it, put it in the IPO (both card and IPO new out of box) did the upgrade and the system works, but I cannot connect with manager. I can open monitor and SSA, but no luck with manager. I have tried both lan and wan, using 42.1 and 43.1, set with my PC set to static and dhcp in both instances. I can ping the appropriate address depending on what port I am in. I have changed ethernet cables. I have tried to go directly to the IP address instead of using the 255.255.255.255. I have connected wireshark and verified the right ip addresses are passing info. I am not sure what to do next. This is more an experiment than anything, but I am wondering what I did wrong. Any suggestions appreciated.
