12441,TCP connections from host to guest drop on host network reconfiguration events. -> fixed in SVN,jglogan,,"I have started seeing this behavior after upgrading to 4.3.4.  It is 100% repeatable on my system, and has a pretty significant impact on productivity.

The forum article I posted is [https://forums.virtualbox.org/viewtopic.php?f=8&t=58909].

Reproduction steps:
{{{
1.) Start guest VM
2.) ssh into guest (localhost:2322 forwarded to guest:22 in my config)
3.) Perform any of the following operations:
  a.) disable, then enable WiFi (issue occurs on enable, not disable)
  b.) disable VPN on host (happens with IPSecuritas and NetExtender VPNs on my system)
  c.) enable VPN on host
}}}
Expected behavior: no impact on ssh connection from host to guest

Actual behavior in 4.2.x: same as expected

Actual behavior in 4.3.4: ssh connection terminated, 'Connection to localhost closed by remote host.'

Config:

Host - MacOS 10.8.5,
Guest - Ubuntu 13.04, 3.8.0-34-generic x86_64
Guest network - Paravirtualized network (NAT, natdnshostresolver enabled so that I can resolve VPN hostnames, but I have tested with it disabled and the same issue occurs)
