# This device is a pure AP — no routing, no NAT.
|
|
#
|
|
# Zones:
|
|
# mgmt — management interface (192.168.255.11)
|
|
# input: ACCEPT (SSH, ping reachable from MGMT network)
|
|
# forward: REJECT (nothing routes through mgmt)
|
|
#
|
|
# lan — client bridge (eth0.2, LAN ports)
|
|
# input: REJECT (clients cannot SSH into the AP itself)
|
|
# forward: ACCEPT (traffic passes through to MikroTik for firewalling)
|
|
#
|
|
# iot — IoT bridge (eth0.5, wifi only)
|
|
# input: REJECT (IoT devices cannot reach the AP itself)
|
|
# forward: ACCEPT (traffic passes through to MikroTik, which allows
|
|
# internet only and blocks all internal networks)
|
|
#
|
|
# uplink — internet uplink via MikroTik vlan6 (192.168.6.2/24)
|
|
# input: REJECT (no inbound connections from internet side)
|
|
# output: ACCEPT (AP itself initiates outbound — opkg, NTP, etc.)
|
|
# forward: REJECT (AP does not route client traffic through uplink)
|
|
#
|
|
# wwan — LTE modem uplink (Orange PL, /dev/cdc-wdm0, always-on)
|
|
# input: REJECT (no inbound from LTE)
|
|
# output: ACCEPT (AP itself uses LTE for outbound when uplink unavailable)
|
|
# forward: REJECT (default; overridden by explicit uplink→wwan forwarding rule)
|
|
# masq/masq6: enabled — NAT all traffic exiting via wwan (own + forwarded)
|
|
#
|
|
# No forwarding rules between zones — all inter-zone policy is on MikroTik.
