My home network has an OpenVPN server installed and working. I can connect into that network from Windows machines using the OpenVPN client software and everything works fine.
I have an Ubuntu laptop with the OpenVPN client installed. I can connect to the OpenVPN server using the client and the client.ovpn provided by my server; however, I cannot ping or access machines on the VPN once connected. Running a ping to a network machine results in this:
$ ping 192.168.2.3
PING 192.168.2.3 (192.168.2.3) 56(84) bytes of data.
From 192.168.2.136 icmp_seq=1 Destination Host Unreachable
From 192.168.2.136 icmp_seq=2 Destination Host Unreachable
From 192.168.2.136 icmp_seq=3 Destination Host Unreachable
The same thing works fine from Windows, so there must be an issue with how the routes are getting configured on the Ubuntu client, but I can't figure out what it is. I flushed my firewall rules on the client just in case.
Here's the output from route -n
before and after the VPN connection:
107.15.x.x
is the VPN network's public IP.
172.27.x.x
represents the VPN's virtual network.

Any idea what I need to do to solve this?
