- On **Equuleus**, when redirecting traffic from a PPPoE interface to an Intermediate Functional Block interface, the redirected PPPoE interface is completely deleted from the configuration when VyOS boots.

- On **Crux**, when redirecting traffic from a PPPoE interface to an Intermediate Functional Block interface, you may get the following message when committing:
```
vyos@pppoe-client# set interfaces input ifb0
[edit]
vyos@pppoe-client# commit
[edit]
vyos@pppoe-client# set interfaces ethernet eth2 vif 35 pppoe 0 redirect ifb0
[edit]
vyos@pppoe-client# commit
[ interfaces ethernet eth2 vif 35 pppoe 0 redirect ifb0 ]
Exiting subroutine via next at /opt/vyatta/sbin/vyatta-qos.pl line 315.
```
Then the configuration looks ok, but there must be something wrong, because when an outbound shaping policy is applied to ifb0, shaping does not take place.
