Following post is an reference guide or scrapbook, which have working codes for following.

  1. Dual WAN PCC with 2 DSL modems [configured in bridge mode] and dialing is done via mikrotik
  2. Port forwarding various ports [as required] from the internet to local web server
  3. PPPoE Server

Note: I have used SOURCE BASE classifier in this example, to avoid common load balancing problems like https links breakup, buffering issues stuck problem etc etc : )

Just to remind this is not a copy paste version. its not complete export version. I modified the data for reference. Read them carefully for better understanding. You can pick any section of your choice or as required. I will add more sections later …

For port forwarding under PCC, You need to play with the PCC router. Logic is simple, let router knows the return path !! You should mark incoming connection to remember incoming interface, and then via route responses , using that marked packet to send them via same interface.
First You need to mark new incoming connections from WANs with connection marks (to identify via which wan request came from). & then for outgoing packets of these previously marked connections, you need to mark routing, to make them use the right WAN (via which packets arrived)

NETWORK DETAiLS :

Mikrotik LAN Interface name = Local
Mikrotik WAN 1 interface name = WAN1
Mikrotik WAN 2 interface name = WAN2

Mikrotik LAN IP Address = 192.168.0.1
WEB Server on LAN side = 192.168.0.10

Mikrotik IP POOL for LAN DHCP = 10.0.0.1/8
Mikrotik IP POOL for PPPoE Users = 172.16.0.0/16

Let’s Start ….
