TL-ER6120 V3 - Policy Routing - Mode priority not working as it should
We have multiple WAN ports. When I try to create a few Policy Routing rules, with Mode = Priority, it's not working as it should. Sometimes it's jumping from one to another wan port. Even if both ports are online, and only one port are configured for this rule. As I understand, I should have access only for one specifit wan port which is configured for this rule? Isn't it? When I set Mode = Only. It's working well. But now if my configured WAN port will be offline, the rule will turn off at all whole route?
Please explain me anyone. Is it ok? Or maybe, I misunderstand something?
Another question, If I have 4 WAN ports active, how to set only one main port through which all traffic must travel? Of course only if this port is alive-online.
Thanks for any help.
