Load Balancing 3 WAN's & 1 LAN RG750G

RouterOS General

Hi Guys,

I hope someone can help me out here.
We have 3 WAN connections from 3 diffrent ISP, currently we are using and EDIMAX BR6614 and is really easy to setup as it has a built in web interface, only problem it only allows 20 port forwarding rules.

Ok so this is our setup

WAN
10.11.1.1
10.11.2.1
10.11.3.1

LAN
10.10.1.1

internal to external NAT’d
We need to have all internal to external traffic balanced across the 3 WAN’s
We need to set rules that specific traffic i.e port 25 is blocked for all except for 1 ip
We need port 25 from that IP for go across a specific WAN interface based on the destination
HTTPS needs to work

external to internal
Default block everything
expect we need to forward specific ports to internal IP’s
and drop packets from specific hosts.

Now have seen some doc’s on PPC, but I was hoping someone could explain this in winbox, or if there is another download-able web interface I can use that will allow for all of this.

Awesome thanks.

Terminal commands are 1:1 in winbox.

/ip firewall mangle add chain=prerouting action=accept

translates to: click the IP button to fan out the menu, click the Firewall button. Go to the Mangle tab, click the + button to add, set the chain field to ‘prerouting’ and set the action field to ‘accept’.

After a few days of using it winbox will not seem complex anymore. It is worth learning. An interface that lets you do whatever you want is necessarily complex. Otherwise you end up with something that is easy to use, but has arbitrary restrictions, such as only allowing 20 port forward rules…
