6.38.1 and 6.37.4 eoip problem

RouterOS General
1

my config:

  1. CCR10009 – > 2. SXT SA5 → 3. SXT AC lite

  2. pppoe server on eoip interface

  3. eoip to ccr inside bridge with virtualAP

When 3. is connected to phisical interface(with bridge) - everything is ok.
when i switch clients SXT AC lite to virtualAP with eoip, I’m unable to do bandwitch test to CCR (Tx are ok, but RX stops at 600 bps - then pppoe is dissconected)
the only thing that helps is downgrading SXT SA5 to 6.34.4 (changing on CCR or SXT SA5 does nothing)

iis this normal behavior or a bug?
