Use -s 500 to 1500 to simulate some-how real traffic situation. I guess you have a point-to-point link between the two offices, connected to a router? Do you administer these routers? Do know your bandwidth utilization? Are you sure your link is OK? check this with your service provider. Either you link is bad or you use all your available bandwidth. > > I want to use my freebsd box running 6.0 but just want to know if > some one could recomend me wich ports to check to see if i can find > wich device is causing this problem. FreeBSD can not help you much with this. Unless FreeBSD is the router in question. Or you could pass all traffic from a FreeBSD box in order to know what's going on. something like this central-switch------FBSD------router-1=====router-2 [--------------------LAN--------------------] [-----WAN-----]
