[Gate-users] Generic Repeater Problem

[Xinjie Cao]

Hi Maxime,

Thanks a lot for reminding me these details, otherwise I might still be
confused why my question always sink in the sea. Really appreciate your
patience and reply, I am happy to get help from you here as a rookie in the
mailing list. As for the question, I think I have found the solution. Thank
you again!

Warm regards,
