I’ve searched and searched and this scenario is not yet covered, please help if you can.
2 X Modems/WAN1 & 2 ===> DHCP-Client1 & 2 on hEX ports 1 & 2 → port3 → SXT <----> SXT<—>PBPro ===>2 X mANT15s with PPPoE servers on both.
I want to send PPPoE-Server1 traffic through WAN1 and PPPoE-Server2 traffic through WAN2, NO balancing and NO failover as OSPF is running.
What’s the best, easiest to understand and simplest way to do this?
Thank you kindly for any help!
Ahahahaah!!! 
Sorry is the first time than I read “NO Balancing NO Failover” 
Ahahahaah!!!
Seriously, OSPF for what? Only for the 2 mANT15s?
Without any schema or /export, is hard to “visualize” what you know and how you have configured the devices.
If is my network (ignoring MGMT VLAN) I increase the MTU on all path
make two VLAN from hEX to wlan1 in each mANT and put on hEX local VLAN interfaces the two pppoe
and I configure inside hEX where each pppoe must go, over WAN1 or over WAN2 with simply routing rules.
Actually no, this is just 2 sectors serving 40+ clients off one of 4 other base stations I have in this area, I want to use the 2nd WAN without balancing. I actually cover over 100Km2 with 35 base stations and 40 WAN connections, but that’s not my concern right now or yours.
So balancing breaks many things, TV streaming is the biggest challenge right now, care to offer a solution to my question?
To be clear: what you ask is perfectly feasible, for example, by VLAN you can use only one virtual cable from each mANT to single WAN.
Think about it.
I’m trying, as you can see, to give some suggestions, but the data to think about are so few.
Now it’s late (here) I hope someone can help you without having more information.
Good night.
In other words the quality of response will be determined by the quality of information provided.
Things that help.
a. network diagram and architecture
b. set of requirement that talk about what users/devices on the network should be able to do without any mention of a config
c. post your config
