Re: strange issue with ssh on F20 on DSL/VPN (more addl info)
I wanted to provide a further update in that the problem with
openconnect only happens with VPN on the wired network but not when VPN
is used using wireless. Any ideas as to why and how to fix this problem?
Many thanks,
Ranjan

I wanted to add that I have found out that another way to connect to
the F20remote machine (beyond rebooting it) on the DSL/VPN. That is by
disconnecting and reconnecting the VPN. But why should this be so? And
also why does this not happen with the other machines that are not
running Fedora but older Centos/RHEL distributions. And why does it not
matter (and works fine) on a Wifi/VPN connection through a cable modem.

Thanks again for any much-needed help!
