i`v mikrotic v 5.2 installed in dell workstation .
and i`v only 2 NICs 1st used as lan and hot spot interface and the 2nd used as wan and internet interface .
iv 2 internet connections through only the wan interface so iv did the below sittings
:
1 - added 10.0.0.1/8 ip address to the lan interface
2 - added 192.168.0.150/24 and 192.168.1.150/24 to the wan interface while my routers are 192.168.0.1 and 192.168.1.254
3 - i`v added the 8.8.8.8 and 8.8.4.4 as dns servers to my router
so what i need is to merge both of internet connections in the wan interface but with fail over . i mean that if one of my connections goes down i need the internet to my customers working on the secound connection and if both of them are working i need the internet to work on the full capacity for both of internet speed .
i used the below code :
/ip firewall mangle
add action=mark-connection chain=input comment="PCC Mine" disabled=no in-interface=wan new-connection-mark=wlan1_conn passthrough=yes
add action=mark-connection chain=input comment="PCC Mine" disabled=no in-interface=wan new-connection-mark=wlan2_conn passthrough=yes
add action=mark-routing chain=output comment="PCC Mine" connection-mark=wlan1_conn disabled=no new-routing-mark=wlan1 passthrough=yes

/ip firewall nat
add action=masquerade chain=srcnat comment="PCC Mine" disabled=no out-interface=wan
add action=masquerade chain=srcnat comment="PCC Mine" disabled=no out-interface=wan
but if one of the connections goes down all my customers goes down also .
