ipv6

We have multiple Opengear console-servers in the field which are using LTE as the primary connectivity for our out-of-band access. Most of the people would use Opengear Lighthouse to manage and administer their fleet of devices. Due to the rather small amount of devices on our end, we decided to use a more lightweight solution. By using the public IPv6 addresses gathered via LTE (thanks Telekom!) and DynDNS, we are able to connect to the console-servers at any time....

Today, I had a strange issue with IPv6 on my Proxmox VE based Hypervisors. I configured IPv6 for a customer by using a transfer subnet between our gateway router and the virtuel firewall. Additionally, I’ve routed a /56 subnet to be used by the customer onto the firewall and added a few /64s onto the internal interfaces of the customer.

Unter VyOS und EdgeOS gibt es einen Fehler in der Kombination von IPv4 und IPv6 Prefix-Listen in einer gemeinsamen Route-Map. Die Filter für IPv6 werden dabei auch auf IPv4 Subnetze angewendet. Im aktuellen Rolling-Release ist der Fehler bereits behoben. Das Test-Setup besteht aus zwei Routern, die jeweis ein lokales Netzwerk in Form eines /28 Netzes aus dem Bereich 192.168.0.0/16 announcieren. Verbunden sind die beiden Router über ein Transfernetz (100.64.64.0/30), als AS Nummern werden 100 (RT01) und 200 (RT02) verwendet....
