Hello,
It seems that FW's default self signed certificate uses RC4 cipher which is not supported by latest browsers.
You try following steps to change the cipher and test:
1.) "set ssl encrypt 3des sha-1" on the firewall to change the cipher used to access the device from RC4_MD5 to 3DES_SHA-1
# If the step one does not work then you can try change the self signed certificate on the device with 3DES as the cipher:
2. Please follow these steps to generate the certificate:
+ Prior to performing this procedure, you have to delete system self-signedcertificate:
# delete pki object-id system
+ Then follow these steps:
+ Define the certificate attributes:
# Objects>certificates>new>fill in the parameters>select key length as 2048 and RSA > generate a self signed certificate
+ After the security device generates a key pair,to learn the ID number for the key pair, use the following command:
# get pki x509 list key-pair
+ Use this local certficate for managing the device
# Configuration>admin>management>in the certificate drop down select this new certificate and select cipher as des or3 des
Please let me know if this works or not.
Regards,
Rishi
