You need to provide more details about what isn't working. The
tunnel interface has an IP address. I see that there are no packets
transferred though. Does "ip route" show the right routing? How
are you running vpnc? Can you provide the relevant log messages or
vpnc output?

I see this on F28 as well and I'm pretty sure it's been there for a
long time.

It's not relevant. I think there's some trigger related to network
interfaces changing.
never mind ... it's related to some earlier complaining i saw on this list.
as we were debugging, the IT guy casually mentioned that he normally brings
up the VPN via NetworkManager, while I was used to doing it via "sudo vpnc".
"fine," i thought, and humoured him by bringing it up that way ... and it
worked.
argh. so no more command line, only NetworkManager.
