Hi,
We are using Zeroshell in VPN bonding configuration. Everything works fine in bonding and we get very high throughput. We use static routes for tunnel endpoints and default route is used on Bonded interface to push all traffic via Datacenter ZS. Netbalancer is turned off.
Recently we have observed that when the underlying internet connection i.e. PPP reconnects, the corresponding VPN doesn’t come up until we reboot the box from GUI.
The VPN tunnel are configured using UDP but when the tunnel were changed to use TCP, it comes up ok when PPP reconnects but throughput is impacted badly around half of the speed of the bundle.
We tested this on 3.5.0 and 3.6.0. and tunnels stays down post PPP reconnect till we reboot the ZS.
Any pointers will be helpful.
Thanks in advance
Hitesh
