Its 99% udp traffic (voip) and the pbx guys are telling me its straight up packet loss most likely due to windows sockets. I suppose I could flip to a linux type firewall/vpn or I could just raise the sockets limit, Im just not sure where to gather the right data to see if Im hitting any limits. I already set ISA to not have any connection limits and not inspect any packets or do anything like that thinking that could be the case but apparently that has had no result. Our bandwidth is good, I have Solarwinds running on my 6meg pipe on both sides and there is no real errors and usage is peaked at @ 65%. I never hit full throughput. _____ From: Michael B.

The only place where I've needed to do this in the past was on VERY busy web servers and RPC/HTTP servers (a special case of a web server). Regards, Michael B.

The servers are ISA on each side and connected by a 6meg bonded pipe pending a 100meg fiber link to the hosting facility. Anyone think this is rubbish or have any experience with something like this? I know I can increase the sockets pretty easily, I know ISA doesn't have any QoS to handle the traffic correctly but when I told the vendor what I was going to do for them they didn't seem to have a problem with it until the calls came up real choppy. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
