ASA and verizon issue

[Toolshedr6]

Hi,

I have ASA 5540s. I configured internal web server to host a web site.

I have a VIP on netscalers that is set up to reverse proxy to my webserver. Its 80 and 443 traffic.

Everything works fine except for when I'm using Verizon cellular connection(if i'm using Verizon phone through wifi it works fine as well. If i'm using ATT, Sprint etc... everything works fine). On the capture I see re-transmits and drops between ASA and Netscalers (only for Verizon).

Need some advice on how to t-shoot this issue.

could be anything dude, I would compary a capture trhough celular with fully functioning capture.

look at things like MTU, 

your set up is obviously not faulty, its the way Verizon talks to it.

It turn out to be a NAT statement on secondary router on secondary line that active but technically nothing should be going through it
