    I set up an alias LinuxUpdateServer with three entries:

    security.debian.org
    ftp.tu-chemnitz.de
    deb.nodesource.com

    In DNSResolver log it shows

    This seems not to be ok. Is there not enought place to store the IPs from deb.nodesource.com and so they get lost and are renewed next time?

  • Rebel Alliance Developer Netgate

    If the domain uses random sets of addresses, it cannot properly work with hostname aliases. Your client will get a different DNS result than the firewall when either one resolves the domain.

    There is no solution for that unless you hardcode a single static address for that in DNS, which defeats the purpose of their load balancing and could easily break.



  • Yes you are right. I didn't see that the IPs are different.

    Thank you
