Hi, I’m a newer. I have a mikrotik Ros run in vmware as pppoe server which set it to pap only, and have a tenda router as pppoe client.
the tenda router have probability pppoe authentication failed, when change secrets from pap only to chap or replace mikrotik Ros to tp-link router, the issue is gone.
I use wireshark to analyze the traffics, I found that Tenda device send PAP authentication request and ROS pppoe server said ‘authentication failed’, But actually the pppoe secrets’s name and password is correct, if it keep trying to connect, Eventually it will.
I don’t know why will cause it. Is it really ‘authentication failed’? or it trigger by other things.
P.S. how upload my entire wireshark capture? I not found the option.
