Bug ID: 271010
Summary: network traffic to vnet Jail fails one way
Product: Base System
Version: 13.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: bugs@FreeBSD.org
Reporter: Meyser@xenet.de
stable/13 as of today.
transfering data from external to a vnet Jail stalls an timeouts.
Host machine with vnet jail
ftpd inside jail.
Windows PC
Downloading 1G data file via FTP from Jail to Win works.
Uploading 1G data file via FTP to jail stalls and runs in a timeout.
this is the simplified testcase of
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270951
ftpd on host system works without a glich.
perhaps an bridge / epair Problem.
ifconfig -a on host (only igc0 / v310 / v310Hbridge / v310Bsamba are involved)
