LOad Balancing with Failover RouterOS 7+

Hi,

I would like to ask for some help by the configuration of my Mikrotik CCR2004-1G-12S+2XS.
I have the following situation.

  1. My Switch is connected to the router trough SFP
  2. I have 2 WANs on ETH1 and ETH2. Both WANs are modems.
  3. WAN1 is a 500Mb connection with dynamic IP
  4. WAN2 is a 100Mb connection with fixed IP
  5. I would need a configuratuion with Load balancing and Failover:
    a. Load Balancing - (now if i make a new connection which exceed the download capacity in some time trough one of the WANs, than this connection drops - RouterOS6 - this should not happen)
    b. Load Balancing - normally all should use dynamic connection, depending where can communicate with the highest bps.
    c. Load Balancing - some PCs should every time communicate trough the WAN with fixed IP(if possible, than with priority)
    d. if i communicate from the internet with the fixed WAN IP and given port, this should go to defined IP in port. for exampe XXX.XXX.XXX.XXXX:21111 should be forwarded to 192.168.1.25:8000
    e. Failover - If one of the WANs dont work, the whole communication should go trough the second WAN(atm. on my RouterOS6 if the ISP have some problems, i need to disable the modem, because till the modem works, even without real connection, the router try to communicate trough)
    f. Maybe in next time i would extend witha 3rd ISP so the whole configuration should work with more WAN-Ports too.

I would be very thankfull if someone could help.

Hi, What u need is recursive routing.
Configure recursive routing u will be gud to in ur scenario

This might be a nice starting point:
