pppoe gateway issue

RouterOS General
1

I found a grotesque by coincidence show in following picture.As usual, pppoe-out1’s gateway should be 113.68.141.1,and pppoe-out2’s gateway should be 113.68.142.1, it should be two different gateway,but now like what you seen in the picture, it’s the same and it’s neither 141 nor 142,it’s 140. Why?

Question two:
Now I use these two pppoe-out load balancing,if set the same gateway 113.68.140.1 in /ip route and NAT, dose the packet flow which with different routing-mark would go throught one way? and the gateway is the same, mark routing-mark for each packet flow is nonsense,right?

Question three:
Is the network address like 113.68.140.1 in the “address list” set by Mikrotik according to the dynmaic address through some algorithm or just provided by ISP?

113.68.140.1 is remote address provided by ISP

for routes, set ‘gateway=pppoe-out*’ - so you won’t need to set gateway address

Thank Chupaka,it seems work in setting of route,but how about in mangle? There is no “pppoe-out*” options in it.by the way , I am using the PCC load balancing, so I had to set these in mangle ,do you have any others good suggestions?

where do you need that in Mangle?..

The highlight line in the 11.picture.
" add chain=prerouting dst-address=10.111.0.0/24 action=accept in-interface=Local
add chain=prerouting dst-address=10.112.0.0/24 action=accept in-interface=Local "
These two lines I am estreated from “PCC-Mikrotik Wiki”.To set two “dst-address” in mangle prerouting chain it’s a must in “PCC-Mikrotik Wiki”.I consider that these two “dst-address” is the gateway of two separate public IP,but when these two separate gateway became the same one like what I mentioned in the 1.picture,in one word,when the public ip appear like what was shown in 1.picture, what should I set the “dst-address” in the mangle prerouting chain?
I should set:
add chain=prerouting dst-address=131.68.141.1/24 action=accept in-interface=Local
add chain=prerouting dst-address=131.68.142.1/24 action=accept in-interface=Local
or I should set:
add chain=prerouting dst-address=131.68.140.1/24 action=accept in-interface=Local
add chain=prerouting dst-address=131.68.140.1/24 action=accept in-interface=Local

Is there any difference between these two setting? Please think it twice and give a solid theory of your choice. Thanks.

in that example, 10.11?.0.0/24 are internal addresses (either your LAN addresses, or your PPPoE address pool)
