When I powercycle both my router and modem, my router will get the internal ip from the modem that is supplied by my ISP. In order to get the external ip via DHCP, I have to restart the modem, unplug the ethernet going to the router and wait for the modem to finish syncing its connection to the isp. After that I plug back in the ethernet and release/renew via tomato and it pulls the external IP. Any ideas on how to fix this? I need this process to be automated/fixed due to needing remote access after a power outage.
