ASA 5520 with 7.2.1.
I cannot access certain websites. For example, www.nationalunderwriter.com
The capture attach shows asa-ca as a good working capture to compare with a asa-uk which is the bad capture. Note the negotiation is all 0 (ie window is 0). I already tried CCO exceed-mss workaround and still no worky so pretty sure it is not a mss issue
