* fix(sysctl): enable net.ipv4.ip_forward for NAT bridgesLibravatar sommerfeld9 days1-0/+5
| | | | | | | waydroid (and libvirt with finicky guests) need the host to route between their NAT bridge and the upstream NIC. libvirtd usually enables this on demand but it doesn't persist, so the container has no internet on a fresh boot until something else flips the bit.
* feat(net): nftables laptop firewallLibravatar sommerfeld2026-05-131-0/+13
| | | | | | | | | | | | | Default-deny inbound, allow outbound. Scoped to 'inet filter' with 'destroy table' on reload so podman/netavark tables are preserved. - meta/base.txt: add nftables - systemd-units/system/base.txt: enable nftables.service - etc/nftables.conf: laptop ruleset (loopback, ct state, ICMP/ICMPv6 essentials, DHCPv6 client, default-drop input/forward, accept output) - etc/sysctl.d/99-sysctl.conf: rp_filter=2, no redirects, no source-route, log_martians - README.md: firewall section with reload caveat
