Hello,
I am using a MikroTik router with PCC load balancing on 3 WAN links (WAN1–WAN3) for LAN users.
I also have a 4th WAN (WAN4) which I want to use only for remote CCTV/camera traffic coming from external locations to my local NVR.
My Setup:
-
WAN1, WAN2, WAN3 → Used in PCC for normal internet users
-
WAN4 → Dedicated for camera/NVR traffic only
-
Cameras connect from remote public IPs to my NVR via port forwarding
-
NVR is on LAN
-
PCC is already working fine for users
Problem:
When WAN1 has the lowest distance (main route), camera traffic replies go via WAN1 instead of WAN4, causing asymmetric routing and connection issues.
If I make WAN4 priority 1, cameras work, but LAN internet becomes unstable.
I want:
LAN users → Use WAN1–WAN3 via PCC
Camera/NVR traffic → Always use WAN4 (no PCC)
WAN4 should not be used by LAN users
What I Tried:
-
Route distance changes
-
PCC exclusion
-
Mangle marking
-
Policy routing
But traffic still follows default route unless WAN4 is primary.
