My setup is as follows:
RB(PPPOE server) --- Ethernet --- RB(AP Sector *bridged*) --- Wireless --- RB Client(PPPOE client)

Client gets a LLv6 address and a ipv6 default route to pppoe-out1 (with no gateway address)

If I ping the LLv6 address of the PPPOE Server from the client through wlan interface I get a response (OK).
If do the same ping but through the default gateway interface (pppoe-out1) I get hop limit exceeded error.

ROS Version 6.20 on Server, Sector, and Client.

This is the wrong behavior!!!
