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?
