Subject: Connectivity to Brazil

Hello all!!!  First post here

Some carrier, somewhere between us and the service provider is selectively dropping the IKE packets originating from 
our VPN gateway and destined for our Brazil gateway. Other traffic is able to pass, as are the IKE packets coming 
back from Brazil to us. This is effectively preventing us from establishing the IPSEC tunnel between our gateways.

Also something else is awry, for two given hosts on the same subnet (x.y.z.52 and x.y.z.53), they take two wildly 
divergent paths:


For dest  x.y.x.52

Anyone have any insight on to what may be occurring?
