Greetings,
ERX newbie here, running 1.9.0. I have my config set up to acquire IPv6 addresses from Comcast, and it is all working spectacularly well, except the ERX loses all these addresses every ~4 days and I need to reboot to reacquire them. IPv4 is fine. So, can anyone advise me:
1. Is this normal? Is there something I can change in my config to prevent this problem?
2. If not, is there an equivalent to ipconfig /release ipconfig /renew that I can cron 2x/week to reacquire without rebooting, which seems rather brute-force?
Config below.
Thanks!
