Hello guys im here again to ask some help. Im quite new with RouterBoard so ill try explain properly my problem. I just bought a 751U 2HnD with the brand new RouterOS 5.14 (updated today). Im reading the Wiki and the Forum and i found out the PCC (http://wiki.mikrotik.com/wiki/Manual:PCC) i almost got successfull but im got a problem with the second internet link router getting unreachable, the WEIRD thing is, it works for some seconds after that gets unreachable, if i disable the routes (192.168.137.1 routes) it works a little bit than gets unreachable.
Ps: I disabled Interfaces 3 and 4 for testing ( 1, 2, 5 Enabled )
Topology:
Address, NAT, Mangle, Route List:
Next we can see the ISP2 getting unreachable for some reason
Here my script based on PCC Wiki:
/ ip address
add address=172.16.30.10/24 network=192.168.0.0 broadcast=192.168.0.255 interface=LAN
add address=30.30.30.14/24 network=30.30.30.0 broadcast=30.30.30.255 interface=ISP1
add address=192.168.137.2/24 network=192.168.137.0 broadcast=192.168.137.255 interface=ISP2
/ ip firewall mangle
add chain=prerouting dst-address=30.30.30.0/24 action=accept in-interface=LAN
add chain=prerouting dst-address=192.168.137.0/24 action=accept in-interface=LAN
add chain=prerouting in-interface=ISP1 connection-mark=no-mark action=mark-connection new-connection-mark=ISP1_conn
add chain=prerouting in-interface=ISP2 connection-mark=no-mark action=mark-connection new-connection-mark=ISP2_conn
add chain=prerouting in-interface=LAN connection-mark=no-mark dst-address-type=!local per-connection-classifier=both-addresses:2/0 action=mark-connection new-connection-mark=ISP1_conn
add chain=prerouting in-interface=LAN connection-mark=no-mark dst-address-type=!local per-connection-classifier=both-addresses:2/1 action=mark-connection new-connection-mark=ISP2_conn
add chain=prerouting connection-mark=ISP1_conn in-interface=LAN action=mark-routing new-routing-mark=to_ISP1
add chain=prerouting connection-mark=ISP2_conn in-interface=LAN action=mark-routing new-routing-mark=to_ISP2
add chain=output connection-mark=ISP1_conn action=mark-routing new-routing-mark=to_ISP1
add chain=output connection-mark=ISP2_conn action=mark-routing new-routing-mark=to_ISP2
/ ip route
add dst-address=0.0.0.0/0 gateway=30.30.30.1 routing-mark=to_ISP1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.137.1 routing-mark=to_ISP2 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=30.30.30.1 distance=1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.137.1 distance=2 check-gateway=ping
/ ip firewall nat
add chain=srcnat out-interface=ISP1 action=masquerade
add chain=srcnat out-interface=ISP2 action=masquerade
So guys, can you find anything wrong? For testing i just open a terminal and ping 8.8.8.8 (google dns server) and get the reponse OK for ISP1, but ISP2 only works and i disable and enable back, and just for a few seconds because it gets unreachable again.
