Here is the situation; I have an eoip tunnel from main router to a remote router somewhere else in the building. Over this tunnel I have established a pppoe link. It all works up to a point, where I need to set a NAT masquerade rule for pppoe tunnel. Before 6.20.1 I could do this without a problem, with 6.20.1 it gives me error: --- in/out interface matcher not possible when interface [pppoe-xxx-xxx] is slave - use master instead [eoip-xxx-xxx].
The rule is RED as invalid.
