Passing multiple addresses with masks to nwfilter
...ensure that libvirt domains can't spoof IPv6 traffic. It looks like this: <filter name='no-ipv6-spoofing' chain='ipv6-ip' priority='-710'> <rule action='return' direction='out' priority='500'> <ipv6 srcipaddr='$IPV6' srcipmask='$IPV6MASK'/> </rule> <rule action='drop' direction='out' priority='1000'/> </filter> The goal is to allow any traffic coming from the entire prefix (e.g. 2001:db8::/32). This theoretically would work fine when passing in the variables from...

Re: Passing multiple addresses with masks to nwfilter
...n_filters, it sounds like the preferred approach is to use something like: <filter name='no-ipv6-spoofing' chain='ipv6-ip' priority='-710'> <rule action='return' direction='out' priority='500'> <ipv6 srcipaddr='$IPV6[@1]' srcipmask='$IPV6_MASK[@1]'/> </rule> <rule action='drop' direction='out' priority='1000'/> </filter> The documentation reads: Assign concrete values to SRCIPADDRESSES and DSTPORTS as shown: SRCIPADDRESSES = [ 10.0.0.1, 11.1.2.3 ] DSTPORTS = [ 80, 80...

East-west traffic network filter
Hello, I would like to make filter that allows communication only between specified VMs. Those VMs should be specified by their MAC address. The filter should extend clean-traffic but I was not able to get it working with that reference. I have came up with modified clean-traffic which works fine [1]. Is there a way to achieve the same behavior with reference to clean-traffic? Thank you. Best
