Operator identified the block: the home network NATs its own OpenVPN server on
WAN:1197, colliding with the cluster's outbound PIA-on-1197 flow (port-specific,
not a general UDP block — UDP/53 worked in tcpdump). PIA accepts OpenVPN on
53/1194/1197/1198/8080/9201; chose 53 (empirically proven to traverse this net).
- cluster-vars: add PIA_OPENVPN_PORT="53"
- gluetun: OPENVPN_ENDPOINT_PORT=${PIA_OPENVPN_PORT}
- re-enable vpn-egress; DECISIONS-LOG resolution noted
