Firewalld zones/policies for forwarding (Docker bridge → gre-ashburn),
iptables for Docker-specific rules (DNAT, DOCKER-USER, mangle, SNAT).
Both coexist at different netfilter priorities.
See docs/postmortem-ashburn-relay-outbound.md for root cause analysis.

Root cause: Docker FORWARD chain policy DROP blocked all DNAT'd relay
traffic (UDP/TCP 8001, UDP 9000-9025) to the kind node. The DOCKER
chain only ACCEPTs specific TCP ports (6443, 443, 80). Added ACCEPT
rules in DOCKER-USER chain which runs before all Docker chains.
Changes:
- ashburn-relay-biscayne.yml: add DOCKER-USER ACCEPT rules (inbound
tag) and rollback cleanup
- ashburn-relay-setup.sh.j2: persist DOCKER-USER rules across reboot
- relay-inbound-udp-test.yml: controlled e2e test — listener in kind
netns, sender from kelce, assert arrival
- relay-link-test.yml: link-by-link tcpdump captures at each hop
- relay-test-udp-listen.py, relay-test-udp-send.py: test helpers
- relay-test-ip-echo.py: full ip_echo protocol test
- inventory/kelce.yml, inventory/panic.yml: test host inventories
- test-ashburn-relay.sh: add ip_echo UDP reachability test

mia-sw01: Replace PBR-based outbound routing with VRF isolation.
TCAM profile tunnel-interface-acl doesn't support PBR or traffic-policy
on tunnel interfaces. Tunnel100 now lives in VRF "relay" whose default
route sends decapsulated traffic to was-sw01 via backbone, avoiding
BCP38 drops on the ISP uplink for src 137.239.194.65.
biscayne: Add TCP dport mangle rule for ip_echo (port 8001). Without it,
outbound ip_echo probes use biscayne's real IP instead of the Ashburn
relay IP, causing entrypoints to probe the wrong address. Also fix
loopback IP idempotency (handle "already assigned" error).

Normal playbooks should never hardcode hostnames — that's an inventory
concern. Changed all playbooks to hosts:all. The one exception is
ashburn-relay-check.yml which legitimately spans both inventories
(switches + biscayne) and uses explicit hostnames.
Also adds:
- ashburn-relay-check.yml: full-path relay diagnostics (switches + host)
- biscayne-start.yml: start kind container and scale validator to 1
- ashburn-relay-setup.sh.j2: boot persistence script for relay state
- Direct device mounts replacing rbind (ZFS shared propagation fix)
- systemd service replacing broken if-up.d/netfilter-persistent
- PV mount path corrections (/mnt/validator-* not /mnt/solana/*)

Root cause: the doublezero-agent on mia-sw01 manages Tunnel500's ACL
(SEC-USER-500-IN) and drops outbound gossip with src 137.239.194.65.
The agent overwrites any custom ACL entries.
Fix: create a separate GRE tunnel (Tunnel100) using mia-sw01's free
LAN IP (209.42.167.137) as tunnel source. This tunnel goes over the
ISP uplink, completely independent of the DZ overlay:
- mia-sw01: Tunnel100 src 209.42.167.137, dst 186.233.184.235
- biscayne: gre-ashburn src 186.233.184.235, dst 209.42.167.137
- Link addresses: 169.254.100.0/31
Playbook changes:
- ashburn-relay-mia-sw01: Tunnel100 + Loopback101 + SEC-VALIDATOR-100-IN
- ashburn-relay-biscayne: gre-ashburn tunnel + updated policy routing
- New template: ashburn-routing-ifup.sh.j2 for boot persistence

Playbook fixes from testing:
- ashburn-relay-biscayne: insert DNAT rules at position 1 before
Docker's ADDRTYPE LOCAL rule (was being swallowed at position 3+)
- ashburn-relay-mia-sw01: add inbound route for 137.239.194.65 via
egress-vrf vrf1 (nexthop only, no interface — EOS silently drops
cross-VRF routes that specify a tunnel interface)
- ashburn-relay-was-sw01: replace PBR with static route, remove
Loopback101
Bug doc (bug-ashburn-tunnel-port-filtering.md): root cause is the
DoubleZero agent on mia-sw01 overwrites SEC-USER-500-IN ACL, dropping
outbound gossip with src 137.239.194.65. The DZ agent controls
Tunnel500's lifecycle. Fix requires a separate GRE tunnel using
mia-sw01's free LAN IP (209.42.167.137) to bypass DZ infrastructure.
Also adds all repo docs, scripts, inventory, and remaining playbooks.
