ppalias,

Yes, it is setup with a bond of the 6 VPN tunnels. All routing etc is based upon that bond.

Also, Zeroshell is running at both ends on VMware ESXi – each with 512 Meg RAM and two CPU cores.

Running wireshark is showing me a multitude of duplicated ACKs and retransmits etc, so there is definately packet loss.

Also a ping with a large payload size (I chose 1800) is showing RTT between 20ms and 600ms with about every 10th packet lost altogether. This on a service that has no other traffic.

Other single non bonded links sit quite consistently on 30 – 40ms.

What logs to I look at? Looking at the statistics of the bond and the 6 underlying VPN tunnels is showing no errors.

Thanks

Tony
