Slowwww https access from external IP

[Anonymous]

I have two 7100 and a 7060, and when accessing them via the external IP address the interface is horribly slow.

I thought perhaps it was an mtu issue or other?? but that does not seem to be the case.  NAT through the device likewise doe not seem to have issues.

They are all using a sip trunk on the external interface,calls are fine, just the https interface (both admin and phone manager are horrible. 

Thoughts?

Just for grins I added http access with the following:

  permit tcp 123.231.123..0 0.0.0.255  host 123.231.123.231 eq http

nice quick response, but:

  permit tcp 123.231.123..0 0.0.0.255  host 123.231.123.231 eq https

is horribly slow.

Nobody??

Thank you for reporting this behavior.  This is a known AOS issue that is currently under investigation by our design engineering group.  The fix for this issue will be included in a future release for your product, but I do not yet know what specific software revision will contain this fix.  You can subscribe to to receive email notifications about new software releases.  Until this fix is available, use HTTP for quicker access when managing this device.

Thanks,

I would also recommend trying different browsers for the HTTPS management.  I have found that Chrome, in particular, is significantly slower for this type of connection.

Has this problem been fixed yet, and if so in what release? Any recommendations? Does this affect all AOS products, or just the 7000 series?

Our design engineering team is still investigating this problem.  We have seen problems related to the browser type and version being used with the browser client opening up an large number of TCP connections to the AOS HTTPS server. 

Can you provide some more information on the problem you are seeing and what are the browser type and version that is being used?

Thanks,

Charles

I have this problem all the time. Using the latest version of AOS, and the latest version of Chrome. Issue is on TA908e's, Netvanta 3120's, and other AOS product. This has been an ongoing issue for over 2 year now I believe. Box is fast when accessing the web admin through the LAN, but slow as hell over the internet connection even when the box is connected to ultra fast fiber internet connections.

Thanks you for providing this information.  I have a few follow-up questions.

Are you seeing this behavior with other browser types (firefox, IE, etc.)?

Are you seeing the slow connection when using both HTTP and HTTPS over the Internet connection to the AOS device?

When you say "Box is fast when accessing the web admin through the LAN", is that with both HTTP and HTTPS access?

Thanks,

Charles

I experience the same problem.  I temporarily enabled HTTP admin access to see if it is the same.  Actually, it is not nearly as slow as the HTTPS interface.  I would not suggest using HTTP for public admin access, but I will say that the HTTPS access is much slower than HTTP either on the LAN or WAN.  It's been like that for a long time.  Fortunately, SSH is super fast on both.
