Hi all,

i tried set pppoe-server in interface of customers but don’t work.
my pppoe-client have subnet public ip.
Connection work perfectaly.
but tx traffic in ppp-inteface alway 0 packet.
Why?
Bridge port: proxy arp
wan: proxy arp

I’ve probably been unclear

PPPOE-SERVER - WIFI CONNECTION ----RB750(only bridge) —WIFI CONNECTION —routerbard/pppoeclient

pppoe user, assign subnet public ip, and work perfectaly , but in interface ppp-client traffx tx is 0 and rx work .

why?
