50% packet loss ?

Kenneth,

Check for static route to non-existing or dead gateway. For example, if you have two static routes with the same metrics to the same destination, router will try to do a load-balancing between gateways, and if one is down, you will get every other packet lost.

Good luck,

Hi,

Apart from what already told in the previous reply, this behavior could be also caused by ICMP rate limiting

While unlikely, I have also seen this happen when there is load balancing across firewalls or similar devices and there is not a consistent rule set. Any time when load balancing takes place, there is this option, albeit mostly when you use statics or you have some kind of traffic manipulation device (load balancer, firewall, etc).
