Hi,

I have a strange routing issue with openvpn inside a container. I am a fairly new user of openvz. I have openvpn installed in a container. (I had to use a veth device to get routing to work at all.. venet didn't seem to work).

The HN has 2 interface eth0 (10.255.255.1/24 facing DMZ) and eth1 (10.38.0.1/26, internal lan). This box is also the default gw for my network. (10.38.0.0/26). The vpn network is 10.10.0.0/24. I am running openvpn in server mode here its ip is 10.10.0.1. I have 3 clients connecting with vpn ips of 10.10.0.9 and 10.10.0.13. Each client connects properly and can ping each other and other nodes on my lan (10.38.0.50, 10.38.0.3X) and other containers (10.38.0.2 and 10.38.0.3). The other containers utilized the venet device.

The HN can ping the vpn serve 10.10.0.1 but none of the other nodes (10.10.0.9 and 10.10.0.13). Other nodes on my lan can ping the HN and the vpn nodes. My quest is why can the HN not access VPN clients?

I do not have a bridge for veth103.0 and eth1 setup as I don't want one.


HN:
sysctl -p

net.ipv4.conf.default.forwarding = 1
net.ipv4.ip_forward = 1
net.ipv4.conf.eth0.proxy_arp = 1
net.ipv4.conf.eth1.proxy_arp = 1
net.ipv4.conf.all.arp_filter = 1
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
