Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I managed to connect from outside to the corporate network using VPN (OpenVPN plugin of the network-manager). I get my IP address, routing tables etc set up. But I cannot access anything on that network.

I set my computer as DMZ so it's not a NAT issue. My LAN uses 192.168.123.xxx. VPN uses 10.xxx.xxx.xxx address space.

I opened Wireshark and listened to the tun0 device. Packets going out, but nothing received.

I also listened to the eth0 device. Packets are going in from and out to the VPN gateway.

I set up iptables to accept all traffic via the tun devices, but no avail.

Any ideas to make VPN work?

Enabling the LZO compression in the advanced settings of the VPN connection solved the problem for me. (Hope this helps someone out.)
