I have a new ASA 5512-X, out-of-the-box, which I am unable to open the admin web page on.
Laptop - Lenovo Windows 7 64 bit
Browsers - Firefox 28 & IE 11
Java is installed and correct vesrions
ASDM on the 5512 - asdm-66114.bin
ASA Ver - asa861-2-smp-k8.bin
https is enabled and I'm using IP addresses that are allowed connectivity to the 5512
When i browse to https://192.168.1.1/admin I am presented with a certificate error as expected, I accept the certificate, then the page hangs. This happens on both Firefox and IE.
Wireshark shows the TCP 3-way handshake and the TLS/SSL negotiation which is then immediately followed by the 5512 sending SSL data then a FIN,PSH,ACK packet back to my PC. then a load of TCP retransmits from both my PC and the 5512.
Now, I tried a different PC (Dell), same OS, same ver of Firefox but IE ver.9, and did not have any problems being presented with the 'Run ASDM Wizard' page.
Has anyone had a similar issue? Has anyone please got any idea what config on my PC may be at fault?
