We have a situation where we can not connect to  certain ip addresses.  We have worked with the it staff at destinations and they say we are not blocked.

If we send from a DMZ (virtual machine) out another internet connection it works fine.  We believe we have it down to the ASA, or Extreme switch.  We can ping 99% of external locations. But we are not able to reach some sites through various ports or protocols.  We have no rules restricting these IPs.  Other locations work great for email, telnet tests, etc...

Are you sure the IPs are blocked or could it be DNS?  I've had a similar issue and it ended up being an ISP router issue.  Does tracert show the pings failing at your ASA?

Updated info:  Traffic seems to route from other internal switches. Just not this Extreme Summit switch.

We plan an IOS upgrade and a reboot next weekend.  I will continue the thread if that does not fix it.

Thanks

can you reach these same sites using other protocols?  Lets say you are being blocked when trying to access port 80 at a certain site, but will you be blocked if you try to access port 21?

You say when you when you send out another internet connection it works fine.  Where is this internet connection located? is it also connected to the ASA?

Would you be able to post a sanitized configuration output?

We have it solved down to one extreme switch that uses 4 ports aggregated.  

The others switches send out any asa fine.  So it's just a link aggregation issue to work through.
