Hi guys,

Just thought I would update this.

I had a consultant come in last week and we spent some time trying to track 
down the issue. When he connected his laptop outside of the firewalll, 
everything was fine. But behind the firewall, it was horrifically slow.

Eventually, we updated the SonicWALL 2400's firmware, and that seemed to 
resolve the issue. Things have been very snappy since, and I've been able to 
put a Barracuda Web Filter 310 between it and the firewall and still get rapid 
response times. :)

Thanks to everyone that replied with their thoughts!

Evan

I'd recommend this as well.    I've had issues at various clients where they 
could only download at a fraction of their available internet speed available 
and it always turns out they have multiple port mismatch errors (duplexing and 
speed) between the internet handoff, firewall, and potential in-line web 
filters.   Granted that's sort of the opposite of what you're experiencing 
but...  Worth a mention I thought.

I'd start with disconnecting from your SonicWall, configuring and connecting a 
laptop direct, firewall up of course, and see if you still see the latency 
issues.  Assuming you do, you've pretty much eliminated your network as an 
issue and need to point the finger at Comcast..

Subject: Loooooong ping times

Hi peoples,

I have a weird issue, and I've had it for about 3 weeks (don't worry, it's work 
related!)

Our Internet connection has been really slow. Web sites time out half the time, 
and just load really slowly other times.

Our connection is a Comcast connection, and I called then to see if they could 
test the speed. They did, and it seemed okay to them, but then said that we had 
an old cable modem. They replaced the modem, but it made no difference.

When I use speedtest.net, or speedtest.comcast.net. I usually get good 
throughput times (36 Mbps up, 7 Mbps down) but I get a ping time that is almost 
ALWAYS 3146 ms. Sometimes it's 3147, sometimes it's 3145, but it's 3146 90% of 
the time. Weird, huh?!

So, I went to my SonicWALL and unchecked the check box that was set to enable 
the DHCP server. I thought maybe having two DHCP servers (the SonicWALL and my 
own internal DHCP server) was an issue. I don't even know why the DHCP server 
was enabled on the firewall.

So I disabled that, and I'm still having the same issue - very long ping times, 
though now it's somewhat intermittent. At times, I get a ping time of 72ms, and 
the others, it's right back to 3146,

So my question is, where should I be looking to fix this? Essentially, I have 
two DNS servers, one DHCP server (not including the SonicWALL,) Then I have our 
firewall, and then the cable modem. That's it.

Help? I have no clue how to troubleshoot this.
