I have a fairly fresh install of Ubuntu 18.04, and I'm trying to use vpnc to connect to a remote network.
On a wired connection, everything works fine.
On wifi, it appears to connect (doesn't display any errors when connecting). However my connection to the outside world stops working (no ping to 8.8.8.8, for instance).
Here's the command I'm running:
sudo vpnc /etc/vpnc/myConfigFile.conf
Here's the contents of the config file:
DPD idle timeout (our side) 0
IPSec gateway my.vpn.gateway.gov
IPSec ID ipsec
IKE Authmode psk
IPSec secret ipsec
Local Port 10008
NAT Traversal Mode natt
No Detach
Xauth username <myUsername>
Xauth password <myPassword>
And here's what's in /var/log/sysLog:

I'm not really sure how to interpret the sysLog entries, or even if that's the right place to look for clues. I'm not even sure whether this is a problem with my 18.04 settings, a vpnc problem, a network problem, or what. Answers I've found to similar questions seem to focus on firewall settings, but I haven't installed a firewall. Would appreciate some guidance.
