Hi,
I applied this to 2.5 and used the build system to build windows
installer using windows-nsis/build-snapshot
I tested the windows client against Linux 2.4
The test was:
Connect to first server, receive DHCP 10.*8*.0.6 (net30)
Idle 10 mins / Transfer some data / disconnect
Edit the config file to connect to a new server
(This was an exact copy of first server on a new --port
and with a new --server subnet / PKI identical)
Connect to second server, receive DHCP 10.*9*.0.6 (net30)
Idle 10 mins / Transfer some data / disconnect
No problems encountered.
Note: I *was* able to replicate the original bug using
windows 10 / openvpn 2.4.0 and the same procedure as above.
I am confident that this resolves the problem for Win10.
ACK for W10
Regards
