Hi , if someone have ever face this problem and give me a hint how to deal with that i will be very happy… Here The problem
I have a fiber access and for example i got my first range for example 10.0.156.128/25 with gateway at 10.0.156.129. Now this range is almost full. So i ask a new /25 range i got. So now i have the range 10.0.157.0/25.
The setup is like this on a RB600.
(BRIDGEWAN (Proxy ARP Enabled) With ETH1)
BRIDGEWAN IP : 10.0.156.132/25
Route : 0.0.0.0/0 to 10.0.156.129
So i add to the BRIDGEWAN a new ip of the new range
BRIDGEWAN IP : 10.0.157.2/25
And add route : 0.0.0.0/0 to 10.0.157.1
After that i go to mangle and add a prerouting mark over source address 10.0.156.0/25
And another mangle prerouting mark over source address 10.0.157.0/25
And add the routing mark corresponding to each gateway in routes.
And add a pppoe client to use the new range. For the internet all is working but we have a BIG problem. If a host over the 10.0.157.0/25 range want access to a host in the 10.0.156.0/25 range its not working…
So if someone have a clever idea to solve this problem i pay the beer
